Joan needed $100 to buy a graphing calculator for her math class. Her
neighbor will pay her $5 per hour to baby sit and her father gave her $10 for
mowing the lawn. What is the minimum number of hours she has to baby sit in
order to pay for her calculator?

Respuesta :

Answer: 20 hours

Step-by-step explanation:

The equation can be easily figured out if you take the amount of money needed and divide it by the amount of money per hour.

In this example; 100/5 = 20

To check, you can multiply 20 by 5 and see that it equals 100.
