Charlie is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.

Company A charges $127 and allows unlimited mileage.
Company B has an initial fee of $55.00 and charges an additional $0.90 for every mile driven.
For what mileages will Company A charge at least as much as Company B? Use m for the number of miles driven, and solve your inequality for m .

a=127
b=55+.9m
127=55+.9m
72=.9m
m=80

I think it has to be written as
m<= 80
can anyone clarify - Rachal, Saturday, February 5, 2011 at 9:56am
if the answer should be m<=80 I don't have an equal answer option. Thanks
