Question

Maria charges $5 per hour for babysitting. She wants to calculate the total amount of money she will earn this week. What variable is needed to calculate her earnings?.

Answer 1

To calculate Maria's earnings for the week, we need to know the total number of hours she worked as a babysitter during that week.

Let's call this variable "h" (for hours worked).

Once we know the value of "h," we can multiply it by the rate Maria charges per hour ($5) to get her total earnings for the week.

So the equation to calculate Maria's earnings (E) for the week would be:

E = $5/h * h

Or, simply:

E = $5h
