First, we'll find out how much Lee makes for an hour.

We'll use the rule of three:

22 hours.....................$132

1 hour......................... $ x

22*x = 132

x = 132/22

x = $6/hour

To determine how much Lee will make for 15 hours, we'll just have to multiply the number of hours by the pay rate.

15hours*$6/hour = $90

Therefore, Lee will be payed $90 for 15 hours worked.

$ 132 : 22 hr =  $ x : 15 hr

When you do this, you must first find his hourly rate. You do this by dividing the amount of money earned by the number of hours worked

$ 132/22 hr = $6/ 1 hr

To find how much Lee will make in 15 hours, multiply the top and bottom by 15.

$ 6(15) / 1 (15) hr

= $ 90 / 15hr

Therefore, Lee will earn $90 if he works 15 hours
