Question

Bob 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 $46

 and an additional 60

 cents for every mile driven.

Company B charges an initial fee of $30

 and an additional 80

 cents for every mile driven.

For what mileages will Company A charge less than Company B?

Write your answer as an inequality, using m

 for the number of miles driven.

Answer 1

46 + .6m =< 30 + .8m

16 < .2m

16/.2 = 80 < m

80 miles or more and Plan A is less expensive than Plan B

at 80 miles, both cost $94, at more than 80 miles, A is cheaper
