A brownie has 480 total calories, and 240 of those calories come from fat. What percent of the total calories comes from fat?

1. Let p equal the percent of calories from fat. 2. The sentence translates to 240 equals p times 480. 3. Divide both sides by 480 to get p equals 0.5. 4. Convert 0.5 to percent form to get 50%. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 3 "Math Models", section 3.2 Solve Percent Applications_
