Question

A truck can be rented from a Company A for $80 a day plus $0.20 per mile. Company B charges $50 a day plus $0.30 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost for Comany A a better deal than Company B's?

Answer 1

less than 300 miles

Explanation:

let x be the unknown mile

Company A

0.20x + 80

Company B

0.30x + 50

How many miles must be driven in a day to make the rental cost for Comany A a better deal than Company B's?

We can make an inequality

0.20x + 80 > 0.30x + 50

80 - 50 > 0.30x - 0.20x

30 > 0.10x

300 > x or x < 300
