Kaitlin is going to rent a truck for one day. there are two companies she can choose from, and they have the following prices. company a has no initial fee but charges 90 cents for every mile driven. company b charges an initial fee of $65 and an additional 40 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.

The equation for Company A: c = .90m where c = cost and m = miles driven
The equation for Company B: c = .40m + 65 where c = cost & m = miles driven

Setup:
Company A > Company B
.90m > .40m + 65
.50m > 65                     Subtracted .40m from both sides of inequality
m > 130                        Divided both sides of inequality by .50
Company A will charge more than Company B after 130 miles.
