Discounts are offered everywhere, be it on clothes, shoes, books, etc. To calculate the discount on an item, you must know the list price or original price of the item and the discount percentage. The calculation would be List Price x Discount Percentage = Discount Amount. For example, if a shirt that costs \$50 is on sale for 20% off, to calculate the discount, multiply the original price by 0.2. In this case, you will get \$10, which is 20% of \$50. So, the final cost of the shirt would be \$40.
