Answer:

x + y <= 55

8.5x + 12y >= 350

Explanation:

We use a system of inequalities to solve this question.

I am going to say that:

x is the number of hours working at the window-washing job.

y is the number of hours working at the tutoring job.

You can work a maximum of 55 hours a week.

This means that:

x + y <= 55

You need to make $350 in order to cover your expenses. Your window-washing job pays $8.50 an hour and your tutoring job pays $12 an hour.

This means that:

8.5x + 12y >= 350

The system is given by:

x + y <= 55

8.5x + 12y >= 350
