Liza bought a T-shirt for $12 and 3 pairs of jeans. She had a coupon for $ 2 off the price of each pair of jeans and spent a total of $87 before tax. What was the price for one pair of jeans?

Answer 1

Let p = the price of each pair of jeans

p-2 is the price actually paid for each pair of jeans, with coupon.

3(p-2) is the amount for 3 pairs of jeans

3(p-2) + 12 is the total she spent = 87

3(p-2)=75

p-2=25

p=27
