Example Question #111 : Percentage
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?
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
()
Then, the price was decreased by 20%, to $16.80.
()
It might be tempting to just increase the original price by 20%, but the percent increase and the percent decrease must be performed together.

Example Question #111 : Percentage
Jacob bought a leather wallet for a final price of $32.73. It had been marked down by 15%. Jacob had also used a 10% off coupon, calculated after the 15% off. What was the original price of the wallet?
Taking 10% off the price is the same as paying 90% of the price; just as taking 15% off the price is the same as paying 85% of the price. Taking 85% of the original price and then 90% of the new price is quickly found by multiplying .90 and .85 together. Using algebra:
Example Question #211 : Arithmetic
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?
$393.75
$525.50
$367.50
$281.50
$157.50
$367.50
$375 + $150 = $525
Sale price is 30% off or (0.3)($525) = $157.50
Subtract the discount from the initial price: $525 – $157.50 = $367.50
Example Question #212 : Arithmetic
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?
$4.00
$4.20
$0.80
$5.00
$3.40
$4.20
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
Example Question #213 : Arithmetic
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?
$70.25
$60.50
$67.50
$75.50
$90.75
$67.50
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.
Example Question #13 : How To Find The Sale Price
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?
Howard, by $9.00
Howard, by $10.75
They pay the same price
Carlita, by $9.00
Carlita, by $10.75
Carlita, by $9.00
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.
Example Question #11 : Sale Prices
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?
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

A ring costs . It is then marked up . What is the current price?
Example Question #1283 : Act Math
Ann wants to buy a sweater that's off. She also has a coupon for off the sale price. (This coupon is applied after the price due to the off sale is calculated.) After the sale discount and the coupon, how much will the sweater cost?
To find the sale price, first find % of $:
$
Subtract this amount from to find the sale price:
Finally, subtract the coupon:
