A store discounts an item. Once the amount of discount is known, how is the sale price found?
AOriginal price minus the discount
BOriginal price plus the discount
CDiscount divided by the original
DDiscount times the original price
Answer & Solution
Correct answer: A. Original price minus the discount
1. The discount model has two lines: the amount of discount and the sale price.
2. The sale price equals the original price minus the amount of discount.
3. The sale price should always come out less than the original price, so adding the discount cannot be right.
