Nancy is very happy with the service at the hotel she is staying in. She wants to tip the room service waiter 15 percent of the food bill, which is $120.75. How much should she tip?

Question

10% is 12.075
Half of that is 6.0375
so 15% is 18.1135
Round down to 18.11 since you can't tip a part of a penny. Or up to 18.12 if she's feelin' supa generous.
look mother, no calculator.
