Possible Answers:$128

$160$208

$272$240

$208 Explanation: (320) / (0.8) = 400. The couch has been marked down an additional 40% from the sale price of$320.  $320 * 0.6 =$192.  $400 –$192 = $208. Example Question #2 : How To Find The Sale Price Mary wants to buy a new skirt. It was originally$30, but is marked 20% off. She also received a coupon for 15% off the sale price. How much will Mary pay for the skirt?

$10.50$19.50

$20.40$23.90

$20.40 Explanation: 20% off means that the new price of the skirt will be 80% of the original price:$30(100%  – 20%) = $30(80%) Converting the percent to a decimal gives:$30(0.8) = $24.00 There is an additional 15% off the sale price of$24.00, so the final price is 85% of the sale price:

$24(100% – 15%) =$24(85%)

Again converting the percent to a decimal gives:

$24(0.85) =$20.40

$125$200

The next day, the store ran a sale of 20% off all items. What is the difference in price, in percentage terms, between the initial price of the shoes and the sale price? Possible Answers: The price increased by 1.5% The price increased by 4% The price increased by 10% The price decreased by 10% The price decreased by 4% Correct answer: The price increased by 4% Explanation: To find the price after the initial 30% increase by the manager, you must multiply the original price by 1.3. Then, to find the price after the 20% off sale, you must multiply the new price by 0.8. The original price, therefore, is being multiplied by 1.3*0.8 = 1.04, indicating a 4% overall increase. Example Question #5 : How To Find The Sale Price A shirt is originally priced at$54.  It is on sale for 60% off, and Jeff has a coupon for an additional 15% off the reduced price.

Example Question #1 : How To Find The Sale Price

A video game console with a list price of $500 is marked down 20%. If Katie gets an employee discount of 10% off the sale price, how much does she pay for the video game console? Possible Answers:$340

$360$350

$450$400

$360 Explanation: First find the sale price. Multiply the list price by .2 and subtract that from the list price. 500 – 500 * .2 = 500 – 100 = 400. Now take the employee discount from the new price, 400 – 400 * .1 = 400 – 40 = 360, so Katie would pay$360 for the video game console.

Example Question #1 : How To Find The Sale Price

A shirt, originally $50, is on sale for 20% off. If Andrew has a coupon that takes 15% off the reduced price, what does he pay? Possible Answers:$37.00

$34.00$32.50

$10.00 Correct answer:$34.00

The shirt is on sale for 50 x .8 = $40. If Andrew takes another 15% off, he will pay$40 x .85= $34.00 Example Question #8 : How To Find The Sale Price A blue dress is marked down 15%. What is the sale price of the dress if the regular price is$150?

$103.50$140.00

$137.50$115.25

$127.50 Correct answer:$127.50

Explanation:

There are two ways to work this problem.

The first way is to find the amount of the discount and subtract from the original price: 0.75 * 150 = 22.50, then 150 – 22.50 = 127.50

The second method finds the sales price directly: 100% = % Discount + % Sales Price or 1 – % Discount = % Sales Price

1 – 0.15 = 0.85, so the sales price is 0.85 * 150 = 127.50

Example Question #9 : How To Find The Sale Price

Gina wants to purchase a new television. It was originally $500, but is marked 25% off. She also received a coupon for 10% off the sale price. How much will Gina pay for the television? Possible Answers:$337.50

$375.25$350.00

$102.50$465

$337.50 Explanation: 25% off means that the new price of the television will be 75% of the original price:$500(100%  – 25%) = $500(75%) Converting the percent to a decimal gives:$500(0.75) = $375.00 There is an additional 10% off the sale price of$375.00, so the final price is 90% of the sale price:

$24(100% – 10%) =$375(90%)

Again converting the percent to a decimal gives:

$375(0.9) =$337.50

So, we choose C.

Example Question #1 : How To Find The Sale Price

The grocery store is having a sale on cereal.  The sale is 20% off each box if you buy 3 boxes of the same type and 40% off each box if you buy 5 boxes of the same type.  You purchase one box of puffed rice priced at $3.50, three boxes of bran flakes priced at$4.25 and five boxes of granola priced at $5.00. What is the total price after the discount is applied. Possible Answers:$28.70

$10.00$28.50

$25.00$15.00

$28.70 Explanation: Puffed rice: 1 box at full price =$3.50

Bran Flakes: 3 boxes at 20% off of $4.25 = (3 * 4.25) * 0.20 = (12.75) * 0.20 =$2.55

Cost = $12.75 –$2.55 = $10.20 Granola: 5 at 40% off of$5.00 = (5 * 5.00) * 0.40 = (25) * 0.40 = $10.00 Cost =$25.00 – $10.00 =$15.00

Total Cost = $3.50 +$10.20 + $15.00 =$28.70
