You can put this solution on YOUR website! Car rental agency A will rent a compact car for $35 per day and an additional charge of $0.24 per mile. Car rental agency B will charge only $0.16 per mile but charges $41 per day. If Adam wanted to rent a car for three days, how many miles would Adam have to drive to make car rental agency B a better bargain?
--------
A Company cost: C(x) = 35(3) + 0.24(# of miles)
B Company cost: C(x) = 41(3) + 0.16(# of miles)
---------------
When is B a better bargain?
When B costs less than A for 3 days rental.
-----------
41(3) + 0.16(# of miles) < 35(3) + 0.24(# of miles)
6(3) < 0.08(# of miles)
# of miles > 225 (# of miles Adam would have to drive to make B a better bargain.
