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" value of the dinner before the gratuity is applied is $243 Part: the value of the added gratuity $43.74 %: this is what we are looking for, so this is where we will put our variable (x). ^part⁄_whole = ^%⁄₁₀₀ ^43.74⁄₂₄₃ = ^x⁄₁₀₀ Cross multiply and solve for x: ^43.74⁄₂₄₃ = ^x⁄₁₀₀ 243 * x = 43.74 * 100 243x = 4,374 243x/243 = 4,374/243 x = 18 So, $43.74 is 18% of $243.
