Question

A store has a 20% off sale on pants. With this discount, the price of one pair of pants before tax is $15.20. What was the original price of the pants?

(Please explain every step with detail)

Answer 1

Explanation:

This is the equation for which you need to have values:

The sale price is equal to the original price - twenty percent of the original price

We know the sale price is 15.20, what we don't know is the original price, x. So we will fill in that equation above with numbers and variables:

15.20 = x - .2x and

15.20 = .8x so

x = 19

That's the original price of the pants. Check it just to make sure (but I promise it's correct! ; ) )
