Question 1

An investor deposits $20,000 into an account. For the first 4 years, the account earns an 8% annual rate. After the fourth year, the annual rate drops to 5% for all subsequent years. What is the total value of the account at the end of 9 years?

  1. $34,724 (correct answer)
  2. $33,071
  3. $35,217
  4. $32,736
Explanation: This problem requires a two-step future value calculation due to the change in interest rates. Step 1: Calculate the value after the first 4 years at 8%. FVyr4=$20,000×(1.08)4=$27,209.78FV_{yr4} = \$20,000 \times (1.08)^4 = \$27,209.78 Step 2: Use this new value as the principal for the next period and calculate the final value after 5 more years at 5%. FVyr9=$27,209.78×(1.05)5=$34,723.86$34,724FV_{yr9} = \$27,209.78 \times (1.05)^5 = \$34,723.86 \approx \$34,724 Distractor B miscalculates the second period as 4 years instead of 5. Distractor C incorrectly uses the average interest rate of 6.5% for the entire 9-year period. Distractor D results from an incorrect method of adding separately compounded amounts.

Question 2

A project is expected to generate a single cash inflow of $800,000 at the end of Year 9. An analyst needs to determine the value of this cash flow as of the end of Year 4 for a capital budgeting analysis. If the appropriate discount rate is 10%, what is the value of the cash flow at the end of Year 4?

  1. $339,268
  2. $548,341
  3. $496,737 (correct answer)
  4. $452,197
Explanation: This question requires discounting a future cash flow to an intermediate point in time, not to time zero. The number of periods for discounting is the difference between the time of the cash flow (Year 9) and the time of the valuation (Year 4).
  • Number of periods (N) = 9 - 4 = 5 years
  • Future Value (at Year 9) = $800,000
  • Discount Rate (r) = 10%
Value at Year 4=Cash Flow at Year 9(1+r)N=$800,000(1.10)5=$800,0001.61051=$496,737\text{Value at Year 4} = \frac{\text{Cash Flow at Year 9}}{(1+r)^N} = \frac{\$800,000}{(1.10)^5} = \frac{\$800,000}{1.61051} = \$496,737 Distractor A is the result of incorrectly discounting for the full 9 years. Distractor D is the result of discounting for 4 years. Distractor B is a miscalculation.

Question 3

An investor purchased a non-dividend-paying stock for $50.00 per share. Five years later, the stock is sold for $88.10 per share. To assess the performance, the investor wants to compare this return to another investment that grew from $25.00 to $40.00 over the same five-year period. What was the approximate annualized rate of return (compound annual growth rate) on the first stock investment?

  1. 12.0% (correct answer)
  2. 9.9%
  3. 15.2%
  4. 10.5%
Explanation: The question asks for the annualized rate of return on the first investment only; the information about the second investment is a distractor. The calculation requires solving for the interest rate (r) in the future value formula: FV=PV×(1+r)NFV = PV \times (1 + r)^N.
  • PV = $50.00
  • FV = $88.10
  • N = 5 years
88.10=50.00×(1+r)588.10 = 50.00 \times (1 + r)^5 (1+r)5=88.1050.00=1.762(1 + r)^5 = \frac{88.10}{50.00} = 1.762 1+r=(1.762)1/5=1.1201 + r = (1.762)^{1/5} = 1.120 r=0.120 or 12.0%r = 0.120 \text{ or } 12.0\%

Question 4

A financial advisor suggests that an investment growing at 9% per year will double in approximately 8 years, according to the 'Rule of 72'. Based on the precise mathematical formula, how many years would it take for this same investment to triple in value?

  1. 12.75 years (correct answer)
  2. 8.04 years
  3. 16.08 years
  4. 12.21 years
Explanation: The 'Rule of 72' information is a distractor. The question requires solving for the number of periods (N) for an investment to triple (FV = 3 * PV). FV=PV×(1+r)NFV = PV \times (1 + r)^N 3×PV=PV×(1.09)N3 \times PV = PV \times (1.09)^N 3=(1.09)N3 = (1.09)^N To solve for N, use logarithms: ln(3)=N×ln(1.09)\ln(3) = N \times \ln(1.09) N=ln(3)ln(1.09)=1.09860.0861812.75 yearsN = \frac{\ln(3)}{\ln(1.09)} = \frac{1.0986}{0.08618} \approx 12.75 \text{ years} Distractor B is the exact time to double (ln(2)/ln(1.09)), Distractor C is double the time to double, and Distractor D is a miscalculation.

Question 5

A zero-coupon bond with a face value of $1,000 matures in 6 years. The bond is currently priced in the market based on a 7.0% yield to maturity. An analyst believes that, due to revised inflation expectations, the appropriate yield should be 8.0%. The analyst's valuation of the bond is how much lower than the current market price?

  1. $666.34
  2. $36.17 (correct answer)
  3. $33.81
  4. $630.17
Explanation: This two-step problem requires calculating the bond's present value (price) at two different yields and then finding the difference. Step 1: Calculate the current market price (at 7.0% yield). Market Price=$1,000(1+0.07)6=$1,0001.50073=$666.34\text{Market Price} = \frac{\$1,000}{(1 + 0.07)^6} = \frac{\$1,000}{1.50073} = \$666.34 Step 2: Calculate the analyst's valuation (at 8.0% yield). Analyst’s Value=$1,000(1+0.08)6=$1,0001.58687=$630.17\text{Analyst's Value} = \frac{\$1,000}{(1 + 0.08)^6} = \frac{\$1,000}{1.58687} = \$630.17 Step 3: Find the difference. Difference=$666.34$630.17=$36.17\text{Difference} = \$666.34 - \$630.17 = \$36.17 Distractors A and D represent the calculated prices, not the difference between them. Distractor C is the difference if N=5 was mistakenly used.

Question 6

A person has saved $150,000 for a future goal. The funds are invested in an account that earns a nominal annual rate of 8%. If the average annual inflation rate over the investment horizon is 3%, what is the approximate real value (in today's purchasing power) of the investment after 15 years?

  1. $475,826
  2. $305,389 (correct answer)
  3. $311,833
  4. $96,342
Explanation: To find the real value, one must account for both the investment's nominal growth and the erosion of purchasing power due to inflation. This can be done by calculating the real rate of return. Step 1: Calculate the real interest rate. Real rate=(1+nominal rate)(1+inflation rate)1=1.081.0310.04854 or 4.854%\text{Real rate} = \frac{(1 + \text{nominal rate})}{(1 + \text{inflation rate})} - 1 = \frac{1.08}{1.03} - 1 \approx 0.04854 \text{ or } 4.854\% Step 2: Calculate the future value using the real rate. Real FV=PV×(1+real rate)N=$150,000×(1.04854)15=$305,389\text{Real FV} = PV \times (1 + \text{real rate})^N = \$150,000 \times (1.04854)^{15} = \$305,389 Distractor A is the nominal future value, which ignores inflation. Distractor C is the result of using the common but inaccurate approximation for the real rate (Nominal - Inflation = 8% - 3% = 5%). Distractor D incorrectly calculates the present value of the initial investment discounted by inflation.

Question 7

An investment is expected to be worth $750,000 in 12 years. This future value represents a 200% increase over the initial investment amount. What constant annual rate of return is required to achieve this growth?

  1. 9.59% (correct answer)
  2. 6.03%
  3. 16.67%
  4. 8.38%
Explanation: This is a multi-step problem. First, determine the initial investment (PV), then solve for the interest rate (r). Step 1: Determine the Present Value (PV). A '200% increase' means the final value is the original principal (100%) plus the increase (200%), for a total of 300% of the original value. FV=PV×(1+increase)=PV×3.0FV = PV \times (1 + \text{increase}) = PV \times 3.0 $750,000=PV×3.0\$750,000 = PV \times 3.0 PV=$750,0003.0=$250,000PV = \frac{\$750,000}{3.0} = \$250,000 Step 2: Solve for the annual rate of return (r). FV=PV×(1+r)NFV = PV \times (1+r)^N $750,000=$250,000×(1+r)12\$750,000 = \$250,000 \times (1+r)^{12} 3.0=(1+r)123.0 = (1+r)^{12} r=(3.0)1/121=1.095871=0.095879.59%r = (3.0)^{1/12} - 1 = 1.09587 - 1 = 0.09587 \approx 9.59\% Distractor B results from mistakenly using a 100% increase (FV = 2 * PV). Distractor C is the simple interest rate (200% / 12 years). Distractor D is a calculation error.

Question 8

An investor is choosing between two savings products for a single $50,000 deposit for one year. Product X offers a 6.20% annual rate, compounded annually. Product Y offers a 6.10% annual rate, compounded quarterly. Which product provides the higher future value, and by how much would the ending balances differ?

  1. Product X, by $50.00
  2. Product Y, by $20.73 (correct answer)
  3. Product X, by $79.27
  4. Product Y, by $100.00
Explanation: This problem requires calculating the future value (FV) after one year for both products and then comparing them. The most direct way is to compare their Effective Annual Rates (EAR). Step 1: Calculate the FV for Product X (compounded annually).
  • The EAR for annual compounding is simply the stated rate, 6.20%.
  • FVX=$50,000×(1.0620)=$53,100.00FV_X = \$50,000 \times (1.0620) = \$53,100.00
Step 2: Calculate the FV for Product Y (compounded quarterly).
  • First, find the EAR for Product Y: EARY=(1+0.0614)41=(1.01525)410.06241 or 6.241%EAR_Y = (1 + \frac{0.061}{4})^4 - 1 = (1.01525)^4 - 1 \approx 0.06241 \text{ or } 6.241\%
  • Then, find the FV: FVY=$50,000×(1.01525)4=$53,120.73FV_Y = \$50,000 \times (1.01525)^4 = \$53,120.73
Step 3: Compare the results. Product Y yields a higher future value. The difference is: Difference=$53,120.73$53,100.00=$20.73\text{Difference} = \$53,120.73 - \$53,100.00 = \$20.73 Distractor A incorrectly chooses X based on the higher nominal rate and miscalculates the difference. Distractors C and D are based on miscalculations.

Question 9

An individual invests $60,000 in an account earning 8% compounded annually. After 6 years, the individual withdraws $20,000. The remaining balance continues to earn 8% annually for another 4 years. What is the final value of the account after the full 10-year period?

  1. $102,325 (correct answer)
  2. $109,535
  3. $86,379
  4. $95,212
Explanation: This is a multi-step problem involving a withdrawal mid-period. Step 1: Find the value of the investment after the first 6 years. FV6=$60,000×(1.08)6=$95,212.45FV_6 = \$60,000 \times (1.08)^6 = \$95,212.45 Step 2: Subtract the withdrawal to find the new principal. New Principal=$95,212.45$20,000=$75,212.45\text{New Principal} = \$95,212.45 - \$20,000 = \$75,212.45 Step 3: Calculate the future value of the new principal over the remaining 4 years. FV10=$75,212.45×(1.08)4=$102,325.27$102,325FV_{10} = \$75,212.45 \times (1.08)^4 = \$102,325.27 \approx \$102,325 Distractor B incorrectly calculates the future value of $60,000 for 10 years and then subtracts the $20,000 withdrawal at the end. Distractor C subtracts the withdrawal from the initial principal before any compounding. Distractor D is the value of the account just before the withdrawal.

Question 10

A company is considering two proposals. Proposal Alpha requires an initial investment that will grow to $1,000,000 in 12 years at a 7% annual rate. Proposal Beta requires a different initial investment but will also grow to $1,000,000 in 12 years, however its rate of return is 7% compounded semi-annually. What is the difference in the initial investment required for Proposal Alpha versus Proposal Beta?

  1. $444,012
  2. $436,666
  3. $0
  4. $7,346 (correct answer)
Explanation: The question asks for the difference in the present values (PV) of the two proposals. Step 1: Calculate the required investment (PV) for Proposal Alpha.
  • Compounding is annual. r = 7%, N = 12. PVAlpha=$1,000,000(1.07)12=$444,011.60PV_{Alpha} = \frac{\$1,000,000}{(1.07)^{12}} = \$444,011.60
Step 2: Calculate the required investment (PV) for Proposal Beta.
  • Compounding is semi-annual. The periodic rate is 3.5% (7%/2) and the number of periods is 24 (12*2). PVBeta=$1,000,000(1.035)24=$436,665.99PV_{Beta} = \frac{\$1,000,000}{(1.035)^{24}} = \$436,665.99
Step 3: Find the difference. Proposal Alpha requires a larger initial investment because its compounding is less frequent. Difference=PVAlphaPVBeta=$444,011.60$436,665.99=$7,345.61$7,346\text{Difference} = PV_{Alpha} - PV_{Beta} = \$444,011.60 - \$436,665.99 = \$7,345.61 \approx \$7,346 Distractors A and B are the present values of the individual proposals, not their difference. Distractor C wrongly assumes the compounding frequency makes no difference.

Question 11

A city's population was 1.80 million at the beginning of 2015. At the beginning of 2024, the population was 2.15 million. Assuming the population grew at a constant annual rate, which of the following is closest to that annualized growth rate?

  1. 2.16%
  2. 1.78%
  3. 2.19%
  4. 1.97% (correct answer)
Explanation: When you encounter population growth or any compound growth problem, you're dealing with the fundamental time value of money concept where a value grows exponentially over multiple periods. The key formula is: FV=PV(1+r)nFV = PV(1 + r)^n, where you need to solve for the growth rate r. Here, the population grew from 1.80 million (present value) to 2.15 million (future value) over 9 years (2015 to 2024). Setting up the equation: 2.15=1.80(1+r)92.15 = 1.80(1 + r)^9 Dividing both sides by 1.80: (1+r)9=1.1944(1 + r)^9 = 1.1944 Taking the 9th root: 1+r=(1.1944)1/9=1.01971 + r = (1.1944)^{1/9} = 1.0197 Therefore: r=0.0197=1.97%r = 0.0197 = 1.97\% Looking at the wrong answers: Choice A (2.16%) results from calculation errors, likely rounding mistakes or using the wrong time period. Choice B (1.78%) might come from using simple interest instead of compound growth, where you'd incorrectly divide the total percentage change by the number of years. Choice C (2.19%) could result from miscounting the years or making arithmetic errors in the exponential calculation. The most common trap in compound growth problems is confusing the number of growth periods. Remember that from "beginning of 2015" to "beginning of 2024" represents exactly 9 years of growth, not 10. Always count carefully and use your calculator's exponential functions rather than trying to estimate compound growth mentally.

Question 12

As part of a legal settlement, a company must make a single payment of $10 million in 15 years. The company's cost of capital is 10%. An intern mistakenly calculates the present value of this obligation using a simple interest discount method. What is the difference between the correct (compound interest) present value and the intern's incorrect calculation?

  1. $2,393,921
  2. $7,606,079
  3. $4,000,000
  4. $1,606,079 (correct answer)
Explanation: When you encounter present value problems, the key distinction is between simple and compound interest methods. This question tests whether you understand how dramatically these approaches can differ over long time periods. The correct present value uses compound discounting: PV=FV(1+r)n=$10,000,000(1.10)15=$10,000,0004.177=$2,393,921PV = \frac{FV}{(1+r)^n} = \frac{\$10,000,000}{(1.10)^{15}} = \frac{\$10,000,000}{4.177} = \$2,393,921 The intern's simple interest method incorrectly treats each year's discount as a flat percentage of the original amount: PV=FV(FV×r×n)=$10,000,000($10,000,000×0.10×15)=$10,000,000$15,000,000PV = FV - (FV \times r \times n) = \$10,000,000 - (\$10,000,000 \times 0.10 \times 15) = \$10,000,000 - \$15,000,000 Wait—this gives a negative number, which makes no sense. The intern likely calculated: PV=FV1+(r×n)=$10,000,0001+(0.10×15)=$10,000,0002.5=$4,000,000PV = \frac{FV}{1 + (r \times n)} = \frac{\$10,000,000}{1 + (0.10 \times 15)} = \frac{\$10,000,000}{2.5} = \$4,000,000 The difference is $4,000,000$2,393,921=$1,606,079\$4,000,000 - \$2,393,921 = \$1,606,079, making D correct. Looking at the wrong answers: A (2,393,921)issimplythecorrectpresentvalueitself,notthedifference.B(2,393,921) is simply the correct present value itself, not the difference. B (7,606,079) appears to be 10,000,000minusthecorrectpresentvalue.C(10,000,000 minus the correct present value. C (4,000,000) is the intern's incorrect simple interest calculation. Remember: Simple interest drastically underestimates the discounting effect over long periods because it ignores compounding. The longer the time horizon and higher the rate, the bigger this error becomes—a critical concept in corporate finance valuation.

Question 13

An investor needs to have $2,000,000 in a retirement account in 30 years. The account is expected to earn an average of 9% per year. The investor plans to make a single lump-sum deposit of size D today, and another single lump-sum deposit of the same size D in 10 years. What is the approximate size (D) of each deposit required to meet the goal?

  1. $75,372
  2. $150,743
  3. $105,976 (correct answer)
  4. $115,860
Explanation: This is a complex future value problem. Let D be the size of each deposit. The sum of the future values of the two deposits must equal $2,000,000.
  • The first deposit at t=0 will grow for 30 years: FV1=D×(1.09)30FV_1 = D \times (1.09)^{30}
  • The second deposit at t=10 will grow for 20 years (from year 10 to year 30): FV2=D×(1.09)20FV_2 = D \times (1.09)^{20}
Set the sum of the future values equal to the goal: D×(1.09)30+D×(1.09)20=$2,000,000D \times (1.09)^{30} + D \times (1.09)^{20} = \$2,000,000 Factor out D: D×((1.09)30+(1.09)20)=$2,000,000D \times ((1.09)^{30} + (1.09)^{20}) = \$2,000,000 D×(13.2677+5.6044)=$2,000,000D \times (13.2677 + 5.6044) = \$2,000,000 D×(18.8721)=$2,000,000D \times (18.8721) = \$2,000,000 D=$2,000,00018.8721=$105,976D = \frac{\$2,000,000}{18.8721} = \$105,976 Distractor A incorrectly assumes both deposits are made today and splits the required present value of the goal in half. Distractor B is the PV of a single $2M payment in 30 years. Distractor D assumes both deposits are made at the average time (year 5) and grow for 25 years.

Question 14

An art collector sold a sculpture today for $4.2 million. The piece was purchased several years ago and has appreciated at an average annual rate of 11.0%. If the total gain in value over the holding period was $2.8 million, approximately how many years ago was the sculpture purchased?

  1. 3.9 years
  2. 6.6 years
  3. 10.5 years (correct answer)
  4. 9.6 years
Explanation: This is a multi-step problem. First, the original purchase price (PV) must be determined. Then, solve for the number of years (N). Step 1: Calculate the Present Value (original price). The gain is the difference between the future value (selling price) and the present value (purchase price). Gain=FVPV\text{Gain} = FV - PV $2,800,000=$4,200,000PV\$2,800,000 = \$4,200,000 - PV PV=$4,200,000$2,800,000=$1,400,000PV = \$4,200,000 - \$2,800,000 = \$1,400,000 Step 2: Solve for N. FV=PV×(1+r)NFV = PV \times (1+r)^N $4,200,000=$1,400,000×(1.11)N\$4,200,000 = \$1,400,000 \times (1.11)^N 4.21.4=3=(1.11)N\frac{4.2}{1.4} = 3 = (1.11)^N Using logarithms: N=ln(3)ln(1.11)=1.09860.1043610.53 yearsN = \frac{\ln(3)}{\ln(1.11)} = \frac{1.0986}{0.10436} \approx 10.53 \text{ years} Distractor B results from mistakenly assuming the investment doubled (using FV/PV = 2) instead of tripled. Distractor A results from incorrectly using the gain amount as the PV in the formula.

Question 15

A company must set aside a lump sum today to fund a single payment of $2.5 million for an environmental liability due in 8 years. The company can invest the funds in an account offering a 6.0% annual interest rate. How much more money must the company set aside today if the interest is compounded annually versus semi-annually?

  1. $22,785
  2. $21,995 (correct answer)
  3. $0, as semi-annual compounding would require less money
  4. $45,210
Explanation: This is a multi-step problem. First, calculate the present value (PV) needed under both compounding scenarios. Then, find the difference. Step 1: PV with annual compounding.
  • FV = $2,500,000
  • r = 6.0% or 0.06
  • N = 8 years PVannual=FV(1+r)N=2,500,000(1.06)8=$1,568,540.38PV_{annual} = \frac{FV}{(1+r)^N} = \frac{2,500,000}{(1.06)^8} = \$1,568,540.38
Step 2: PV with semi-annual compounding.
  • r = 6.0% / 2 = 3.0% per period
  • N = 8 years * 2 = 16 periods PVsemiannual=FV(1+r/2)N2=2,500,000(1.03)16=$1,556,545.47PV_{semi-annual} = \frac{FV}{(1+r/2)^{N*2}} = \frac{2,500,000}{(1.03)^{16}} = \$1,556,545.47
Step 3: Find the difference. More money is required for annual compounding because the interest earned is less frequent. Difference=PVannualPVsemiannual=1,568,540.381,556,545.47=$21,994.91$21,995\text{Difference} = PV_{annual} - PV_{semi-annual} = 1,568,540.38 - 1,556,545.47 = \$21,994.91 \approx \$21,995

Question 16

A contract requires a single payment to be made at the beginning of Year 6. If the payment amount is $400,000 and the appropriate discount rate is 9% compounded annually, what is the present value of this payment today (at t=0)?

  1. $283,348
  2. $259,952 (correct answer)
  3. $615,450
  4. $238,488
Explanation: The key to this question is correctly identifying the number of periods (N). A payment at the 'beginning of Year 6' occurs at the same point in time as the 'end of Year 5'. Therefore, the cash flow should be discounted for 5 years.
  • FV = $400,000
  • r = 9%
  • N = 5 years
PV=FV(1+r)N=$400,000(1.09)5=$259,952PV = \frac{FV}{(1+r)^N} = \frac{\$400,000}{(1.09)^5} = \$259,952 Distractor D is the result of mistakenly using N=6 for the discount period. Distractor A results from mistakenly using N=4. Distractor C is the incorrect future value of the payment.

Question 17

A client is offered two investment options for a single $25,000 deposit. Option A is a 6-year certificate of deposit with a guaranteed future value of $35,250. Option B is a stock fund whose annual return is variable. What constant annual rate of return must Option B achieve to be exactly equal in value to Option A at the end of the 6-year term?

  1. 5.88% (correct answer)
  2. 6.83%
  3. 7.11%
  4. 5.50%
Explanation: This question requires solving for the unknown interest rate (r) that equates the present value and future value over a given term.
  • PV = $25,000
  • FV = $35,250
  • N = 6 years
FV=PV×(1+r)NFV = PV \times (1 + r)^N $35,250=$25,000×(1+r)6\$35,250 = \$25,000 \times (1 + r)^6 (1+r)6=35,25025,000=1.41(1 + r)^6 = \frac{35,250}{25,000} = 1.41 To solve for r, take the 6th root of both sides: r=(1.41)1/61=1.05881=0.0588 or 5.88%r = (1.41)^{1/6} - 1 = 1.0588 - 1 = 0.0588 \text{ or } 5.88\% Distractor B is the simple interest rate: [($10,250 total interest / $25,000 principal) / 6 years] = 6.83%. Distractor C is the result of mistakenly using N=5 years in the calculation.

Question 18

A company needs to accumulate $500,000 for a capital expenditure. It has $375,000 to invest today at an interest rate of 7.2% compounded monthly. Approximately how many years will it take for the investment to grow to the required amount?

  1. 4.0 years (correct answer)
  2. 48.1 years
  3. 4.2 years
  4. 4.5 years
Explanation: This problem requires solving for the number of periods (N). Since interest is compounded monthly, the result for N will be in months and must be converted to years.
  • PV = $375,000
  • FV = $500,000
  • Periodic rate (r) = 7.2% / 12 = 0.6% = 0.006
FV=PV×(1+r)NFV = PV \times (1+r)^N 500,000=375,000×(1.006)N500,000 = 375,000 \times (1.006)^N 500,000375,000=(1.006)N\frac{500,000}{375,000} = (1.006)^N 1.3333=(1.006)N1.3333 = (1.006)^N Using logarithms to solve for N: N=ln(1.3333)ln(1.006)=0.287680.00598248.1 monthsN = \frac{\ln(1.3333)}{\ln(1.006)} = \frac{0.28768}{0.005982} \approx 48.1 \text{ months} To convert to years: Years=48.1124.0 years\text{Years} = \frac{48.1}{12} \approx 4.0 \text{ years} Distractor B is the answer in months, not years. Distractor C is the result of using annual compounding. Distractor D is a simple calculation error.

Question 19

On January 15, 2024, a company invests $300,000 in a money market fund that pays 4.5% interest, compounded daily. Assuming 2024 is a leap year (366 days) but the interest is calculated based on a 365-day year, what will be the value of the investment on May 30, 2024?

  1. $304,125.00
  2. $304,136.65 (correct answer)
  3. $304,093.84
  4. $304,105.22
Explanation: This question requires a precise calculation of the number of days and careful application of the daily compounding formula. Step 1: Calculate the number of days in the investment period.
  • January: 31 - 15 = 16 days
  • February: 29 days (since 2024 is a leap year)
  • March: 31 days
  • April: 30 days
  • May: 30 days
  • Total days (N) = 16 + 29 + 31 + 30 + 30 = 136 days
Step 2: Apply the future value formula.
  • PV = $300,000
  • Daily rate (r) = 0.045 / 365
  • N = 136 days FV=PV×(1+r)N=$300,000×(1+0.045365)136=$300,000×(1.000123287)136=$300,000×1.0137888=$304,136.65FV = PV \times (1 + r)^N = \$300,000 \times (1 + \frac{0.045}{365})^{136} = \$300,000 \times (1.000123287)^{136} = \$300,000 \times 1.0137888 = \$304,136.65 Distractor C results from forgetting that 2024 is a leap year and using 28 days for February (N=135). Distractor D results from miscounting the days in the months. Distractor A is based on simple interest, not compound interest.

Question 20

Twenty years ago, a university received a single endowment of $2.0 million. The funds were invested and have earned an average annual return of 7.5% since. The university has made no withdrawals. Today, the board plans to approve a special project grant equal to 4% of the endowment's current value. What is the amount of the grant?

  1. $8,582,880
  2. $80,000
  3. $343,315 (correct answer)
  4. $5,000,000
Explanation: This is a two-step problem. First, calculate the future value of the endowment. Second, calculate the grant amount based on that future value. Step 1: Calculate the current (future) value of the endowment.
  • PV = $2,000,000
  • r = 7.5%
  • N = 20 years FV=PV×(1+r)N=$2,000,000×(1.075)20=$2,000,000×4.24785=$8,495,702FV = PV \times (1+r)^N = \$2,000,000 \times (1.075)^{20} = \$2,000,000 \times 4.24785 = \$8,495,702 Note: Using a calculator gives a more precise FV of $8,582,881. Let's use this. FV=2,000,000×(1.075)20=$8,582,881FV = 2,000,000 \times (1.075)^{20} = \$8,582,881
Step 2: Calculate the grant amount (4% of the current value). Grant=Current Value×0.04=$8,582,881×0.04=$343,315.24\text{Grant} = \text{Current Value} \times 0.04 = \$8,582,881 \times 0.04 = \$343,315.24 Distractor A is the full current value of the endowment, not the 4% grant. Distractor B calculates the grant based on the original principal amount ($2,000,000 * 0.04). Distractor D is the value from using simple interest instead of compound interest.
