Question

The manager of a department store decided to raise the price of a certain pair of shoes by 30%. 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?

Answer

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.

Question

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. What is the final price Jeff pays for the shirt?

Answer

After 60% off, the shirt is marked down to $21.60 (found by: $54 - $54*0.6 = $21.60). Jeff uses a 15% off coupon, knocking the price down to $18.36 ( found by: $21.60 - $21.60*0.15 = $18.36).

Question

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?

Answer

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.

Question

A dress is priced at $375 and a pair of shoes are $150. If they are both on sale for 30% off, what is price of purchasing them both on sale?

Answer

$375 + $150 = $525

Question

You are shopping for produce that is on sale. Oranges are 20% off and apples are 15% off. If The regular price of oranges are 3 for $1.00 and the regular price of apples is 3 for $2.00. If you buy 3 oranges and 6 apples, how much will it cost?

Answer

Cost of 3 oranges = $1.00

Sales price = $1.00 – (0.20)($1.00) = $0.80

Cost of 6 apples = $2.00 x 2 = $4.00

Sales price = $4.00 – (0.15)($4.00) = $3.40

Total cost = $0.80 + $3.40 = $4.20

Question

An item of clothing is featured in a store's 25% off sale. Karl, an employee, receives an additional 25% of the sale price. If the item originally cost $120, how much would Karl pay for it?

Answer

This problem requires an understanding of percentages and how to appropriately use them. The sale takes 25% of off the original price, by multiplying $120 by 0.25 we get $30, so the sale price is $120 – $30 = $90. We are then told that Karl receives an additional 25% off of the sale price so we multiply $90 by 0.25, we get $22.50, so the price that Karl would pay would be $90 – $22.50 = $67.50.

Question

Max wants to buy a couch at The Furniture Store. The couch he is considering had been marked on sale for 20% off and was selling for $320. The day he comes in to buy the couch, it has been marked down an additional 40% off of the sale price. What is the difference in the original price of the couch and what Max paid for the couch?

Answer

First find the original price of the couch. If $320 represents the price after taking 20% off, then $320 = 80% of the original price. To find the original price, divide (320) / (0.8) = 400.

Then find the "additional sale" price. The couch has been marked down an additional 40% from the sale price of $320. Since "40% off" means that you pay 60% of what you would have, multiply the sale price of $320 by the 60% that Max pays. $320 * 0.6 = $192.

Finally, do the subtraction of the original price minus the price Max paid: $400 – $192 = $208.

Question

Sharon wants to buy a dress priced at . There is a sale that gives her off of the original price. She also has a coupon that gives her an additional off of the purchase price. Ignoring sales tax, how much will Sharon have to pay for the dress?

Answer

The dress is reduced by 60% of the original price, so first we must figure out what 60% of $39.99 is:

0.6*39.99 = 23.99

Since the sale is 60% OFF of the original price, we have to subtract this number from the original price:

39.99- 23.99= $16.

Now, we have to reduce this price by an additional 10%, so we have to find 10% of $16:

0.1*16 = 1.60

Finally, we must subtract this from our sale price of $16:

$16-1.6 = $14.40

Question

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?

Answer

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

A tablet computer listed at an original price of $250 is placed on sale for 20% off the original price. Bob, an employee of the store, gets an additional 30% off the sale price. What price would Bob pay to purchase the tablet computer?

Question

Howard, a store manager, receives a 50% discount off of items sold in the store. However, Howard's discount does not apply to sale items. Howard is welcome to buy sale items but the only discount he will recieve is the 50% off of the original price. Carlita, an employee, receives a 30% discount off of items. When items are on sale Carlita's 30% discount applies to the sale price of the item.

Who would pay more for an item, originally priced at $150, that is featured in the store's 20% sale, Howard or Carlita? And by how much?

Answer

Since Howard's discount applies only to the original price, the price he would be pay can be determined by multiplying 150 by 0.5, which gives $75, this is the price reduction that Howard recieves, coincidentally it is also the price he will pay after taking $75 off of the original price of $150. Carlita first will recieve the 20% sale discount, her employee discount will then apply to the price of the item after 20% has been taken off of the original price. The calculations that will provide the price that Carlita will pay are as follows. 150 * 0.2 = 30, 150 – 30 = 120, 120 * 0.3 = 36, 120 – 36 = 84. So Howard will pay $75, and Carlita will pay $84. Carlita will pay more by $9.

Question

A blue dress is marked down 15%. What is the sale price of the dress if the regular price is $150?

Answer

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

Question

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?

Answer

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.

Question

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.

Answer

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

Question

A store buys a new line of dresses for $15.00 each. They increase this price by 40% when they sell the dresses in the store. This week, the dresses are on sale for 20% off. What is the price of one dress this week?

Answer

The price of one dress is now $16.80. The original price was $15.00. When the dresses were sold in the store, the price was increased by 40%, to $21.00

(15+15\times 0.4=21)

Then, the price was decreased by 20%, to $16.80.

(21-21\times 0.2=16.8)

It might be tempting to just increase the original price by 20%, but the percent increase and the percent decrease must be performed together.
