Question

Cooper ate brunch at a restaurant . The bill came to $15. If he left a 15% tip, how much was the tip. Explain step by step so I know how to solve problems like these.

Answer 1

Hi

X +0.15X = 15

1.15X = 15

X = 15/ 1.15

X = 13.04

Answer 2

2.25

If it is a two digit bill, you move the decimal once on the total bill, and one for the 15%. 15 --> 1.5. 15% -->1.5. Then you multiply both of them
