the percent increase of the bill after adding the tip?
A. 2%
B. 13%
C. 20%
D. 22%

Answer 1

78-65=13 65/13=5 the tip percent is 5

Answer 2

C.20%

Explanation:

To solve the problem you first need to find the part that is the tip.

78-65=13

Then you cross multiply and divide

`(13)/(65)` =
`(x)/(100)`

When you cross multiply and divide you should get 20 for X makeing the tip 20%.
