Question

For the sale season, a store put a 20% discount on a pair of shoes. After the sale season ended, by how much percent should the store raise the price of the same pair of shoes to return it to the original price? A. 10% B. 15% C. 20% D. 25% E. 30%SHOW LESS0

Solution

D. 25%.

A. To return the price of the shoes to the original price after a 20% discount, the store needs to increase the price by more than 20% because the discount was taken from the original price.

B. Increasing the price by 15% would not be enough to return the shoes to the original price after a 20% discount.

C. Increasing the price by 20% would only bring the price back to the original amount before the discount, not the original price.

D. Increasing the price by 25% would be more than enough to return the shoes to the original price after a 20% discount.

E. Increasing the price by 30% would be more than necessary to return the shoes to the original price after a 20% discount.
