Dezohn's restaurant bill was $68.50. He wants to leave an 18% tip. How much should the tip be?

1. Change 18% to a decimal: 0.18. 2. Multiply the decimal by the bill amount: 0.18 x 68.50. 3. This gives 12.33. 4. So the tip should be $12.33. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 6 "Percents", section 6.2 Solve General Applications of Percent_
