Question

The list price of a DVD player is $129. Sam found the player on sale for $90.30. What was the percent discount?

Answer 1

A percent discount of 30%

Step-by-step explanation:

Since $129 represent 100% of the price, then the new price $90.30 represent 70 %

129 * 100 / 90.30 = 70 %

Since from the 100% of the price, it went to 70% of it, there was a discount of 30%

100 - 70 = 30%
