Question

Mrs. Crandall spent $42 on window shades that were on sale for a certain percent discount. The original price of the shades was $70. What percent was the discount?

Answer 1

To calculate the percent you need to:

Subtract the new price from the old price

70 - 42 = 28

Divide this number by the original price

28/70 = 0.4

Multiply this number by 100

0.4 * 100 = 40

The percent of discount was 40% off. What a steal.
