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?

**$3 x 0.85 = $2.55 - cost of markers.**

**Let the original price of paper =P**

**$2.55 + 0.80P = $5.35**

**0.80P = $5.35 - $2.55**

**0.80P =$2.80**

**P = $2.80 / 0.80**

**P = $3.50 - Original price of paper.**

Price she paid for the markers with coupon = 3.00 x .85 = $2.55

Price of paper = P

Price of paper with coupon = .80P

So

2.55 + .80P = 5.35 subtract 2.55 from both sides

.80P = 2.80 divide both sides by .80

P = 2.80 / .80 = $3.50 = original price of the paper
