Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! A=6h
B=45+5h
they are equal when 6h=45+5h
h=45 hours
(45, 270)
At 45 hours, both companies will charge the same, and the total cost will be $270
A=$270
B=45+225=$270
Use company A for h<=45 hours, otherwise use company B.
