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 two pairs of jeans before the discount is applied would be (2 • $50 = $100) Part: "half off" of one $50 pair of jeans would be ($50 ÷ 2 = $25) %: this is what we are looking for, so this is where we will put our variable (x). ^part⁄_whole = ^%⁄₁₀₀ ²⁵⁄₁₀₀ = ^x⁄₁₀₀ Cross multiply and solve for x: ²⁵⁄₁₀₀ = ^x⁄₁₀₀ 100 • x = 25 • 100 100x = 2,500 100x ÷ 100 = 2,500 ÷ 100 x = 25 So, $25 is 25% of $100.
