Question

Sally is buying new school supplies. She used a 15% off coupon on a set of markers that was originally $3.00. She also bought some paper that was 20% off. In total, Sally spent $5.35 after using her coupons. How much was the original price of the paper? A. $2.55 B. $2.80 C. $3.50 D. $4.28

Answer 1

The original price of the paper is $3.50

Explanation:

15% off coupon for the markers

Amount paid on the markers will be;

3- (15% of 3)

= 3-0.15(3) = 3-0.45 = $2.55

So the amount paid for the papers will be;

5.35 - 2.55 = $2.8

let the original price of the paper be x

x - 20% of x = 2.8

x - x/5 = 2.8

4x/5 = 2.8

4x = 2.8 * 5

4x = 14

x = 14/4

x = $3.50
