# Discount

A discount is an amount by which the regular price of an item has been reduced. Discounts can be expressed as dollar amounts, common fractions, or percents.

Examples
Given a bicycle that initially costs \$100 that is discounted 25%, the discount on the bicycle, expressed as a dollar amount, is \$25. Subtracting the \$25 from the original price of \$100 will yield the discounted price of \$75:
 1. 25% = = 0.25 2. 0.25 × \$100 = \$25 3. \$100 - \$25 = \$75
In the above case case, an understanding of percentages makes it easy to translate the percentage value to a dollar amount. Since percentages are ratios expressed as a fraction of 100, the discounted percentage is equal to the discounted dollar amount. If the value that needs to be discounted is not \$100, the percentage discount can be converted to its decimal form and multiplied by the value to be discounted in order to determine the discounted price.

For example, given a 15% discount on an item that costs \$123:
 1. 15% = = 0.15 2. 0.15 × \$123 = \$18.45 3. \$123 - \$18.45 = \$104.55
