Question

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

Answer 1

The answer is 120%.                  

Answer 2

Answer: 20%

Step-by-step explanation:

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

$\frac{60.00}{72.00}=\frac{100}{x}$

$x=\frac{72*100}{60} \\x=120$

Calculate the difference.

$120-100=20$
