Answer 1

Tip formula

In general, the tip amount is the cost times 0. xx and your total including tip, is the cost times 1. xx where xx = the percent you want to leave. If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.
