Question

- Last week Shelley earned $60.00 in tips waitressing. This week she earned $72.00.

What percent more did she make this week than last week?

Answer 1

The answer is 120%.

Answer 2

Answer: 20%

Explanation:

Rule of 3, let's put the money on the left and the percentage on the right of the chart.

`(60.00)/(72.00)=(100)/(x)`

`x=(72*100)/(60) \\x=120`

Calculate the difference.

`120-100=20`
