Answer 1

Answer:

5 hours per week.

Step-by-step explanation:

Let x represent number of hours worked by Sarah per week.

The number of hours worked by Sarah in 12 weeks would be $12x$.

We have been given that Sarah grace has to work 75 hours of community service for her honor society. She has already worked 15 hours.

We can represent this information in an equation as:

$12x+15=75$

$12x+15-15=75-15$

$12x=60$

$\frac{12x}{12}=\frac{60}{12}$

$x=5$

Therefore, Sarah have to work 5 hours per week in order to complete the community service.

Answer 2

5 hours a week to reach her goal.
