Answer:

The original price of the paper is $3.50

Step-by-step 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
