Javier has been saving for a digital camera. he finds one on sale for $67.50. it usually costs $90.00. what is the percent of discount?

1. Find the difference between the sale price and the original price:
90.00 - 67.5 = 22.5
                    = $22.50

2. Find this difference as a percentage of the original price:
22.5 / 90 = 0.25
0.25 x 100 = 25%

The percentage discount was 25%.
