the Smith family went out to dinner and received great service. They decided to leave a 20% tip for their waitress. If their dinner bill totaled $90, how much was the tip? How do I set up the problem to find the answer?

Answer 1

Let T = amount of tip given by the family

T = (90)(0.20)

T = 18

The tip given by the family is $18.
