Question 1

A household recorded the following water use:

  • January: 2,800 gallons
  • February: 2,400 gallons
  • March: 3,000 gallons
  • April: 2,700 gallons

Its conservation goal for the first five months is an average of no more than 2,700 gallons per month. No single month may be above 3,100 gallons.

What is the most water the household can use in May and still meet both parts of the goal?

  1. 2,600 gallons, which produces the required five-month average (correct answer)
  2. 2,700 gallons, which equals the stated monthly average
  3. 2,500 gallons, which is needed to offset March's use
  4. 3,100 gallons, which stays within the single-month limit
Explanation: When a question asks you to find a maximum value that still meets a stated goal, you're dealing with a constraint problem — you need to work backward from the goal to find what's allowable. Here's how to think through it: the household wants an average of no more than 2,700 gallons over five months. That means the total for all five months combined cannot exceed 2,700×5=13,5002{,}700 \times 5 = 13{,}500 gallons. Add up the first four months: 2,800+2,400+3,000+2,700=10,9002{,}800 + 2{,}400 + 3{,}000 + 2{,}700 = 10{,}900 gallons. Subtract from the allowed total: 13,500−10,900=2,60013{,}500 - 10{,}900 = 2{,}600 gallons remaining for May. That makes A correct — 2,600 gallons is the maximum May usage that keeps the five-month average at exactly 2,700. Now let's look at why the other choices miss the mark. B sounds appealing because 2,700 is the stated monthly average, but using 2,700 in May would bring the total to 13,600 — pushing the average above the 2,700 limit. C claims 2,500 is needed to "offset" March's high usage, but this reasoning is vague and unsupported — the math shows 2,600 is the correct ceiling, not 2,500. D is the trickiest trap: 3,100 does satisfy the single-month rule, but it completely ignores the average constraint. A question with two conditions requires satisfying both. Study tip: When a problem has multiple rules, solve for each one separately, then choose the answer that satisfies all of them. The most restrictive condition wins.

Question 2

Zone 2 shipping charges:

  • Up to 5 pounds: $8
  • More than 5 pounds through 10 pounds: $11
  • More than 10 pounds through 15 pounds: $15

Packages are rounded up to the next whole pound. Rural delivery adds $3. Buying the label online reduces the listed shipping charge by $2, but it does not reduce the rural fee.

A rural package weighs 6.2 pounds, and its label is purchased online.

What is the total shipping cost for the package?

  1. $12, after applying both the online reduction and rural fee (correct answer)
  2. $9, after rounding the weight and applying the online reduction
  3. $11, because the package falls in the middle weight range
  4. $14, after adding the rural fee to the listed charge
Explanation: When a question involves multiple shipping rules applied in sequence, slow down and apply each rule one at a time — skipping a step is the most common mistake. Start with the weight. The package weighs 6.2 pounds, and the rules say to round up to the next whole pound, giving you 7 pounds. A 7-pound package falls in the "more than 5 pounds through 10 pounds" range, so the base charge is $11. Now apply the adjustments. Purchasing the label online reduces the listed charge by 2,bringingitto∗∗2, bringing it to **9**. The rural delivery fee adds $3, and the rules explicitly state this fee is not reduced by the online discount — so it's added separately: $9 + 3 = \12 . Choice A correctly captures all three steps. Choice B gets the rounding and online discount right but forgets to add the rural fee entirely, stopping at $9. Choice C uses the correct base rate of $11 but applies neither adjustment — no online discount, no rural fee — as if the package were a standard, in-person transaction. Choice D adds the rural fee to the listed charge of $11 without applying the online discount, arriving at $14, which means it skips the $2 reduction the buyer earned by purchasing online. A useful strategy: when a problem lists multiple rules, write them out as a checklist — weight rounding, base rate lookup, discounts, surcharges — and check each one off in order. This prevents you from stopping early or skipping a modifier that changes the final amount.

Question 3

A clinic has these open room blocks:

  • 9:10–9:40 a.m.
  • 10:00–10:50 a.m.
  • 11:20 a.m.–12:00 noon

A new-patient intake lasts 40 minutes. After every intake, the room must remain available for 10 additional minutes so staff can reset it. The intake and reset must both fit within one open block.

At which time can the clinic schedule a new-patient intake?

  1. 9:10 a.m., using the first available room block
  2. 10:00 a.m., using the full 50-minute room block (correct answer)
  3. 11:20 a.m., ending the intake exactly at noon
  4. 11:30 a.m., leaving 30 minutes before noon
Explanation: When a question gives you time blocks and a multi-part task, your job is to check whether all requirements fit inside a single block — not just part of them. Here, every intake needs 40 minutes of room time plus 10 minutes for reset, meaning the total block required is 40+10=5040 + 10 = 50 minutes. The second block, 10:00–10:50 a.m., runs exactly 50 minutes, which means a 40-minute intake followed by a 10-minute reset fits perfectly with no time wasted and no time shortage. That makes B the correct answer. Here's why the others don't work: A fails because the 9:10–9:40 block is only 30 minutes long — not enough for even the intake alone, let alone the required reset afterward. Scheduling there would cut the intake short. C is a tempting trap: 11:20 a.m. to noon is 40 minutes, which covers the intake — but leaves zero time for the 10-minute reset. The problem states both must fit within the block, so this option ignores half the requirement. D is where many students stumble: 11:30 a.m. to noon is only 30 minutes, which isn't enough for a 40-minute intake at all, regardless of reset time. A good strategy for these scheduling problems: always add up every time requirement before checking blocks, then compare that total to each block's length. Writing out a quick equation — task+buffer=total needed\text{task} + \text{buffer} = \text{total needed} — prevents you from accidentally matching only one part of the requirement to a block.

Question 4

Monthly assistance fee for a household of three, based on adjusted income:

  • $0–$2,600: no fee
  • $2,601–$2,900: $15 fee
  • $2,901–$3,200: $35 fee
  • Above $3,200: not eligible for assistance

Adjusted income equals gross monthly income minus an allowable childcare deduction. The deduction is limited to $200, even when actual childcare costs are higher.

A household earns $3,250 per month and pays $350 per month for childcare.

What fee should the household pay under this schedule?

  1. $15, after subtracting the full childcare cost from gross income
  2. $35, after subtracting the maximum allowable childcare deduction (correct answer)
  3. No fee, because childcare expenses lower the household's income
  4. No assistance, because gross income is above the highest range
Explanation: When a question gives you a schedule with rules and exceptions, your first job is to apply all the rules in order — not just the ones that seem most obvious. Here, that means using the adjusted income formula before looking up the fee bracket. The passage tells you that adjusted income equals gross income minus the childcare deduction, but caps that deduction at $200 — even if actual costs are higher. The household earns $3,250 and pays $350 in childcare, but only $200 is allowable: $\3,250 - $200 = $3,050 A monthly adjusted income of $3,050 falls in the $2,901–3,200bracket,whichcarriesa∗∗3,200 bracket, which carries a **35 fee**. That makes B correct. A is a trap for students who subtract the full $350 childcare cost, arriving at $2,900 and landing in the $15 bracket. The passage explicitly limits the deduction to $200, so using the actual cost violates the rule. C suggests childcare expenses eliminate the fee entirely, which would require the adjusted income to fall below $2,601. Even with the maximum deduction, $3,050 is well above that — childcare reduces income, but not enough to reach the "no fee" range. D tempts you to stop at the gross income of $3,250, which exceeds $3,200 and looks ineligible. But gross income isn't what the schedule uses — adjusted income is, and that calculation brings the household back into eligibility. Study tip: When a passage defines a special calculation or sets a cap on something, always apply that rule before touching the answer choices. Skipping it is the most common mistake on benefit-schedule questions.

Question 5

Supply records:

  • Gloves: 36 on hand, 12 reserved, reorder point 25, no incoming shipment
  • Masks: 20 on hand, 8 reserved, reorder point 25, 15 arriving in 2 days
  • Soap: 14 on hand, 2 reserved, reorder point 15, 12 arriving in 5 days
  • Paper: 40 on hand, 15 reserved, reorder point 20, no incoming shipment

The office places an order when available supply is below the reorder point. Available supply equals the amount on hand minus reserved items, plus shipments arriving within the next 3 days.

Which supplies should the office reorder now?

  1. Masks and soap, because both are currently below their reorder points
  2. Gloves and masks, because reservations reduce both available amounts
  3. Gloves and soap, because their available supplies are below the set points (correct answer)
  4. Soap and paper, because later shipments and reservations are not counted
Explanation: When a question gives you a formula and a table of numbers, your job is to apply that formula consistently to every item before comparing to a threshold. Here, available supply = (on hand) − (reserved) + (shipments arriving within 3 days). Only shipments arriving within 3 days count — anything beyond that window is excluded. Let's run the numbers for each supply:
  • Gloves: 36 − 12 + 0 = 24 → reorder point is 25 → 24 < 25 ✓ needs reorder
  • Masks: 20 − 8 + 15 = 27 → reorder point is 25 → 27 ≥ 25 ✗ no reorder needed
  • Soap: 14 − 2 + 0 = 12 → reorder point is 15 → 12 < 15 ✓ needs reorder (the shipment arrives in 5 days — outside the 3-day window, so it doesn't count)
  • Paper: 40 − 15 + 0 = 25 → reorder point is 20 → 25 ≥ 20 ✗ no reorder needed
Gloves and soap fall below their reorder points, making C the correct answer. Choice A is wrong because masks have an incoming shipment within 3 days that pushes available supply above the reorder point. Choice B incorrectly includes masks (which clears its reorder point) and excludes soap. Choice D incorrectly excludes paper's reservations from the calculation and misidentifies soap's shipment timing — it arrives in 5 days, so it's already excluded by the formula. Your strategy: always define "available" using the exact formula given in the passage before comparing anything to a threshold. Resist the urge to eyeball "on hand" numbers alone — the formula is the whole game.

Question 6

Nora's completed work schedule:

  • Monday: 8:00 a.m.–4:30 p.m.; 30-minute unpaid break
  • Tuesday: 9:00 a.m.–5:00 p.m.; 30-minute unpaid break
  • Wednesday: 8:30 a.m.–3:00 p.m.; 30-minute unpaid break
  • Thursday: 10:00 a.m.–4:00 p.m.; no break

Nora needs 30 paid hours for the week. On Friday, she starts at 9:00 a.m. and will not take a break.

What is the earliest time Nora can leave on Friday and still have 30 paid hours?

  1. 11:00 a.m., after working 2 paid hours
  2. 11:15 a.m., after working 2.25 paid hours
  3. 12:00 noon, after working 3 paid hours
  4. 11:30 a.m., after working 2.5 paid hours (correct answer)
Explanation: When a question asks you to find a missing work shift, your job is to work backwards: calculate the paid hours already completed, subtract from the goal, and determine what's still needed. Start by finding Nora's paid hours for Monday through Thursday. Remember, unpaid breaks get subtracted from total time on the clock.
  • Monday: 8:00 a.m.–4:30 p.m. = 8.5 hours − 0.5 = 8 paid hours
  • Tuesday: 9:00 a.m.–5:00 p.m. = 8 hours − 0.5 = 7.5 paid hours
  • Wednesday: 8:30 a.m.–3:00 p.m. = 6.5 hours − 0.5 = 6 paid hours
  • Thursday: 10:00 a.m.–4:00 p.m. = 6 hours − 0 = 6 paid hours
8+7.5+6+6=27.5 paid hours8 + 7.5 + 6 + 6 = 27.5 \text{ paid hours} She needs 30 total, so Friday requires: 30−27.5=2.5 paid hours30 - 27.5 = 2.5 \text{ paid hours} Starting at 9:00 a.m. and adding 2.5 hours brings her to 11:30 a.m. — making D the correct answer. Choice A (11:00 a.m.) only accounts for 2 hours, leaving her 0.5 hours short. Choice B (11:15 a.m.) assumes 2.25 hours are needed — a miscalculation of the weekly total, likely from adding the break times incorrectly. Choice C (12:00 noon) overstates the remaining hours needed by a full half hour. Study tip: Always separate clock time from paid time before adding anything up — that single step catches the most common errors on workplace math questions.

Question 7

Community class registration:

  • Computer Basics: capacity 12, enrolled 12, waitlist 3
  • Budgeting: capacity 15, enrolled 11, waitlist 0
  • Resume Writing: capacity 10, enrolled 8, waitlist 2

A class is canceled if fewer than 9 people are enrolled by the deadline. People on a waitlist do not count as enrolled. Participants from a canceled class may transfer only into open seats in a class that will run.

Which statement correctly applies the registration rules?

  1. Resume Writing will run because its enrollment and waitlist total 10 people.
  2. Computer Basics can accept three transfers because three people are waiting.
  3. All Resume Writing participants can transfer into the Budgeting class.
  4. Resume Writing will be canceled, and at most four participants can enter Budgeting. (correct answer)
Explanation: When a question gives you rules and a table of numbers, your job is to apply each rule carefully — not combine numbers in ways the rules don't allow. Start with Resume Writing: it has 8 people enrolled. The cancellation rule says a class is canceled if fewer than 9 people are enrolled. Since 8 < 9, Resume Writing is canceled. That makes D the answer to investigate further. Now check the transfer part: canceled participants (8 people) may move into open seats in a class that will run. Budgeting has a capacity of 15 and 11 enrolled, leaving 15−11=415 - 11 = 4 open seats. So at most 4 of the 8 Resume Writing participants can transfer into Budgeting. D states exactly this — Resume Writing is canceled and at most four can enter Budgeting. A is wrong because it counts the waitlist toward enrollment. The rules explicitly say waitlisted people do not count as enrolled. Resume Writing has 8 enrolled, not 10, so it doesn't meet the threshold to run. B is wrong because Computer Basics is already at full capacity (12 enrolled, capacity 12). There are zero open seats, so it cannot accept any transfers regardless of how many people are on the waitlist. C is wrong for two reasons: Resume Writing has 8 participants, but Budgeting only has 4 open seats — all 8 cannot transfer in. The key strategy here: always apply rules one at a time and use only the numbers each rule specifies. Watch for answer choices that mix categories (like enrolled + waitlist) that the rules keep separate.

Question 8

Copy shop price list:

  • 1–49 black-and-white pages: 12 cents per page
  • 50–99 black-and-white pages: 9 cents per page
  • Color covers: $1.50 each
  • Members receive 10% off black-and-white printing only.

A member orders 60 black-and-white pages and two color covers.

What is the total cost of the member's order?

  1. $7.56, after reducing the entire order by 10%
  2. $8.40, without applying the member discount
  3. $7.86, after discounting only the printing charge (correct answer)
  4. $9.18, after using both page-rate levels
Explanation: When a question combines a tiered price list with a partial discount, your job is to apply each rule to the right part of the order — not the whole thing at once. Here's how to work through this problem. The member prints 60 black-and-white pages. Because 60 falls in the 50–99 range, the rate is 9 cents per page: 60×$0.09=$5.4060 \times \$0.09 = \$5.40 The member discount of 10% applies to black-and-white printing only, so: $5.40×0.10=$0.54 discount  ⟹  $5.40−$0.54=$4.86\$5.40 \times 0.10 = \$0.54 \text{ discount} \implies \$5.40 - \$0.54 = \$4.86 The two color covers are not discounted: 2×$1.50=$3.002 \times \$1.50 = \$3.00 Total: $4.86+$3.00=$7.86\$4.86 + \$3.00 = \$7.86 That confirms C is correct. A is wrong because it applies the 10% discount to the entire order, including the color covers — but the price list explicitly limits the member discount to black-and-white printing only. B skips the discount altogether, giving you the full undiscounted total of $5.40 + $3.00 = 8.40—arealnumber,butitignoresthemembershipbenefitentirely.∗∗D∗∗(8.40 — a real number, but it ignores the membership benefit entirely. **D** (9.18) incorrectly uses the 12-cents-per-page rate (the 1–49 tier) instead of the correct 9-cents rate for 60 pages, then likely skips the discount too — two errors stacked together. The key strategy here: when a discount has a stated restriction, underline or circle that restriction before you calculate. On multi-part pricing problems, handle each component separately, then combine at the end.

Question 9

Weekday bus schedule from Oak Park:

  • Bus 1 leaves at 7:20 a.m. and arrives downtown at 7:55 a.m.
  • Bus 2 leaves at 7:50 a.m. and arrives downtown at 8:25 a.m.
  • Bus 3 leaves at 8:20 a.m. and arrives downtown at 8:55 a.m.

The health clinic is a 12-minute walk from the downtown stop. Patients must arrive by 8:45 a.m.

What is the latest bus a patient can take and still arrive at the clinic on time?

  1. Bus 1, leaving Oak Park at 7:20 a.m.
  2. Bus 2, leaving Oak Park at 7:50 a.m. (correct answer)
  3. Bus 3, leaving Oak Park at 8:20 a.m.
  4. None of the buses arrives early enough.
Explanation: When a question asks you to work backward from a deadline, the key is to chain your time calculations in reverse — start at the required arrival time and subtract each step to find your latest possible departure. Here's how to work through it: The clinic deadline is 8:45 a.m., and the walk from the downtown stop takes 12 minutes. That means you must arrive downtown no later than 8:33 a.m. (since 8:45−12=8:338{:}45 - 12 = 8{:}33). Now check each bus's downtown arrival against that cutoff. Bus 2 arrives downtown at 8:25 a.m. — that's before 8:33, leaving you 8 minutes to spare for the walk, putting you at the clinic by 8:37 a.m. Bus 2 is the latest bus that works, making B the correct answer. A (Bus 1) also gets you there on time — arriving downtown at 7:55 a.m. gives you plenty of time — but the question asks for the latest option, so Bus 1 is unnecessarily early, not the best answer. C (Bus 3) arrives downtown at 8:55 a.m. Adding a 12-minute walk means you'd reach the clinic at 9:07 a.m. — a full 22 minutes after the 8:45 deadline. This is the most tempting trap: students sometimes only check departure times instead of doing the full calculation to the final destination. D is incorrect because Bus 2 clearly works. Strategy tip: Always trace the full journey to the final destination before choosing. Questions like this hide the trap in the last leg of the trip — the walk, transfer, or wait — not the main ride.

Question 10

A library meeting room is available from 3:35 p.m. until it closes at 5:00 p.m. A group needs a 45-minute meeting. Staff must have the room for 10 minutes before the meeting to set up and 15 minutes afterward to clean. Reservations may begin at any 5-minute mark.

What is the latest time the group's meeting itself can begin?

  1. 3:50 p.m., giving the group a full 70 minutes before closing
  2. 3:55 p.m., leaving 65 minutes before closing
  3. 4:00 p.m., leaving exactly 15 minutes for cleanup after the meeting ends (correct answer)
  4. 4:15 p.m., allowing the 45-minute meeting to end at closing
Explanation: When a question involves scheduling with multiple time requirements, work backwards from the deadline. Identify every time block that must fit before closing, then find where the meeting itself can start at the latest. Here, the room closes at 5:00 p.m. Before that, staff need 15 minutes to clean up, which means the meeting must end by 4:45 p.m. The meeting itself runs 45 minutes, so counting backward: 4:45−0:45=4:00 p.m.4{:}45 - 0{:}45 = 4{:}00 \text{ p.m.} That's the latest the meeting can begin. Before the meeting, staff also need 10 minutes to set up, meaning the room must be reserved starting at 3:50 p.m. — but the question only asks about when the meeting itself begins, which is 4:00 p.m., confirming C is correct. A is a distraction that references "70 minutes before closing" — this misreads the question entirely, confusing available room time with the latest possible start. B similarly offers a plausible-sounding time (3:55 p.m.) but doesn't come from any logical backward calculation; it just splits the difference between wrong answers. D is the most tempting trap — it correctly identifies that a 4:15 p.m. start would end at 5:00 p.m., but it ignores the required 15-minute cleanup window after the meeting. Staff can't clean up if there's no time left. A good strategy: whenever you see scheduling questions, list every required block (setup, event, cleanup), add them up, and subtract from the deadline. Never assume the event itself can run all the way to closing.
