Question

Caroline spent 61.32 on groceries after using coupons. If she would not have used the coupons the groceries would have been 73.00 what is the total discount Caroline received at the grocery store

Answer 1

The answer to your question is Discount = 16%

Explanation:

Data

Payment = $ 61.32

Original cost = $ 73

Discount = x

Process

1.- Use proportions and cross multiplication to solve this problem. The original cost will be equivalent to 100%.

$73 ------------------- 100%

$61.32 -------------- x

x = (61.32 x 100) / 73

-Simplification

x = 6132 / 73

- Result

x = 84%

2.- Subtract 84% from 100%

Discount = 100 - 84

= 16%
