Musclebound movers charge $85 plus $40 an hour to move households across town.
M(x) = 85 + 40x dollars for x hours of work.
------------------------------------------------
Champion moving charges $60 an hour for cross-town moves.
C(x) = 60x dollars for x hours of work.
------------------
For what lengths of time is champion more expensive?
Solve: C(x) > M(x)
60x > 85 + 40x
20x > 85
x > 4.25 hours
