Sarah Grace has to work 75 hours of community service for her honor society. She already worked 15 hrs. How many hours a week must she work for the next 12 weeks in order to complete her 75 hrs?

Answer 1

If she had to do 75 hours and already did 15, she has 60 left do do (75-15=60).

To complete her service in 12 weeks and do the same amount of hours each week, she will need to do 5 hours each week (60/12=5).

She can also vary the work schedule by doing less in one week and make up the hours in another week.
