- 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?

Respuesta :

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.

[tex]\frac{60.00}{72.00}=\frac{100}{x}[/tex]

[tex]x=\frac{72*100}{60} \\x=120[/tex]

Calculate the difference.

[tex]120-100=20[/tex]

The answer is 120%.
