a shirt is marked 15% off and the sale price is $32.30. what was the original price.

Question

Modeling with Linear Equations.

Answer 1

Let x be the original price. Then

.15x is the amount marked off. So

 

x - .15x = 32.30

.85x = 32.30

 

Divide both sides by .85 gives us

 

x = 32.30 ÷ .85

x = $38
