Question

Celeste has $40 that she plans on using to pay for lunch with a friend, including the tip. She always tips 16%. What is the maximum amount Celeste can spend on the food, so she can be sure to have enough money remaining to cover the tip? Round to the nearest cent.

Answer 1

So, when you add 16% to something, you now have 116% of that something.

 

1.16f = 40

f = 34.48

 

 She can spend up to $34.48 on lunch.
