44 because if you use the equation y=mx+b you would plug in 5.8(5)+15 which equals 44
6.5 hours is equal to:
60 mins x 6 + 30 mins = 390 mins
------------
42.25 / 390 = 13/120
------------
Now there are 60 minutes in an hour, so what we do is multiply 13/120 by 60 to find out how much you earn per hour...
13/120 x 60 = 6.5
--------------
You earn $6.50 per hour.
