A truck can be rented from company A for $80 a day plus $0.60 per mile. Company B charges 30$ a day plus $0.80 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost for Company A a better deal than Company B's?
-------------------
A(m) = 80 + 0.60m
B(m) = 30 + 0.8m
---------------------------
For company A to have a better deal, the truck must be driven more than __ miles per day.
Solve::
80 + 0.6m < 30 + 0.8m
-------
50 < 0.2m
m > 5000/2 = 2500 miles
---------------
