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?

Answer 1

$19

Explanation:

Because we know that $15.20 is 20% off, that means $15.20 represents 80% of the original price. We can find how much 100%, the original cost, is if we found how much 1% costs and multiply that by 100. To find how much 1% costs, you would do 15.20/80 which is 0.19. Then, multiply 0.19 by 100. This results in the original price being $19.
