Carlos 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 an initial
fee of $70 and an additional 40 cents for every mile driven. Company B has no
initial fee but charges 90 cents for every mile driven. For what mileages will
Company A charge more than Company B? Use m for the number of miles driven, and
solve your inequality for m.
A = 70 + 0.40m B = 0.90m A > B 70 + 0.40m > 0.90m 70 > 0.50m 140 > m
For what mileages will Company A charge more than Company B?

For mileages less than 140 miles
