Question

Suppose you pay $24 for a pair of shoes that has been discounted 20%. What is the original price of the shoes? My Teacher wants me to Define the Variables. How do I do that?

Answer 1

X = original cost of shoes
x - .20x = discounted cost of shoes
Add like terms
x - .20x = .80x

Equation

.80x = $24
Divide both sides of the equation by .80.

Answer
x = $30 - original price of the shoes
