Shelby buys four shirts. Each shirt is the same price. she uses a cupón that is worth $8 off her total purchase. She pays less than $52 with the cupón. Write an inequality that represents the costs of one shirt.

An inequality that represents the costs of one shirt is x < 15.

Explanation:

No. of shirts bought by Shelby = 4

let cost of each shirt be x

then total cost of 4 shirt = 4*x = 4x

Given that she uses the discount coupon worth $8

Total price paid by Shelby = total cost of 4 shirt - value of discount coupon

= 4x - 8

It is also given that She pays less than $52 with the cupón

thus,

Total price paid by Shelby less than $52

4x - 8 < 52

=> 4x < 52+8

=> 4x< 60

=> x < 60/4

=> x < 15

An inequality that represents the costs of one shirt is x < 15.
