We can use the percent formula to solve. The percent formula is below: ^part⁄_whole = ^%⁄₁₀₀ Based on the text, these are the values we will plug into the percent formula to solve: Whole: the original "whole" price of the clothes before the discount is applied was $168 Part: the savings from the discount were ($168 - $134.40 = $33.60) %: this is what we are looking for, so this is where we will put our variable (x). ^part⁄_whole = ^%⁄₁₀₀ ^33.6⁄₁₆₈ = ^x⁄₁₀₀ Cross multiply and solve for x: ^33.6⁄₁₆₈ = ^x⁄₁₀₀ 168 * x = 33.6 * 100 168x = 3,360 168x/168 = 3,360/168 x = 20 So, $33.60 is 20% of $168.
