A simple discount is a percent decrease from an item’s original price: the discount amount equals the discount rate multiplied by the original price, and the sale price is the original price minus that amount, or the remaining percent of the original price. Reasoning may be represented with percent bars, ratio tables, decimals, fractions, or equations for familiar rates and money values; the discount is not calculated from the already reduced price. Successive discounts, compound changes, and more advanced reverse-percent problems are not included.
A discount is a percent taken away from the original price.
