Jerry works no more than 20 hours a week during the school year. He is paid $10 an hour for tutoring geometry students and $7 an hour for delivering pizzas for Pizza King. He wants to spend at least 3 hours, but no more than 8 hours, a week tutoring. Find Jerry’s maximum weekly earnings.

Works no more than 20 hours/week

3-8 hours tutoring
Subtract 3-8 from the 20 to give you hours for pizza delivery

So anywhere between 12-17 hours for pizza delivery

To find his maximum weekly hours (keeping in no more than 20 hours)

3 hours tutoring
17 hours pizza

3 x $7 = $. $21
17 x $10 = $170
-----------------------
$191
If he did
8 hours of tutoring
12 hours of pizza

8 x &7 = $56
12 x $10 = $120
------------------------
$176

So he'd be better off working more hours delivering pizza & less doing tutoring
