Answer: A. $25.5

B. $15.3

Step-by-step explanation:

Given : The sale price of every item in a store is 85 percent of its usual price

A. The usual price of a backpack is $30.

Then, the sale price = 85% of (usual price of a backpack)

= 0.85 x ($30)

= $25.5

Hence, the sales price of backpack = $25.5

B. The usual price of a sweatshirt is $18.

Then, the sale price of sweatshirt = 85% of (usual price of a sweatshirt)

=0.85 x ($18)

= $15.3

Hence, the sale price of sweatshirt = $15.3
