Lisa takes a taxi uptown, and the fare is $12.78. She wants to give the driver a 10% tip. If Lisa gives the driver a $20 bill, how much change should she ask for?
You would divide 12.78 by 100 to get 1% then multiply it by 10 then add it to 12.78 the minus it from 20 and the answer is how much change she would need
