What is a store discount?

Many stores—from apparel shops to bookstores—offer a discount on the retail price or, less often, on the sale price. For example, say a sweater that originally costs $50.00 is discounted by 25 percent during a sale at a department store. The customer will actually pay 75 percent (or 75/100 or 0.75) of $50.00. To determine the sale price, multiply $50.00 by 25 percent (50 × 0.25 = 12.50); then subtract the discount from the original price to find the sale price, or $50.00 - $12.50 = $37.50.
