Question

Hong 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 $75 and allows unlimited mileage. Company B has an initial fee of $55 and charges an additional $0.80 for every mile driven. For what mileages will Company A charge less than Company B? Use m for the number of miles driven, and solve your inequality for m.

Answer 1

75=55+.8m

.8m= 20

m= 20/.8

m =25 miles cost the same

<25 use B

>25 use A
