The sale price of every item in a store is 85% of its usual price. a. The usual price of a backpack is $30, what is its sale price? $
25.5

b. The usual price of a sweatshirt is $18, what is its sale price? $

Answer

a. The backpack is $4.50

b. The sweatshirt is $2.70

Step-by-step explanation:

a. 30 x 0.15 = 4.50 (The 0.15 is from the price you are actually paying for the item. Because the item is 85% off, you are paying for 15% of the usual price. 15% as a decimal is 0.15 so you multiply that to the original price to find the amount u will pay.)

b. 18 x 0.15 = 2.70
