Deshaun 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 has no initial fee but charges .70 cents for every mile driven.
Company B charges an initial fee of $50 and an additional .20 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: 0 + .70m
B: 50 + .20m
A>B
.70m > 50 + .20m
m > 100
