Joslynn makes $8.25 per hour babysitting. If she made $123.75 last week, then how many hours did she work last week?

We already know that Joslynn makes $8.25 per hour.

Equation:

123.75 divided by 8.25= worked hours

123.75 divided by 8.25 = 15 hours

So last week Joslynn worked 15 hours to make $123.75.
