Problema Solution

A truck can be rented from Company A for $90 a day plus $.50 per mile. Company B charges $20 a day plus $.60 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost for Company A a better deal than Company B's?

Answer provided by our tutors

Let 'x' represent the miles per day.

Company A will charge: 90 + 0.50x

Company B will charge: 20 + 0.60x

The rental cost for Company A is a better deal than Company B's means:

90 + 0.50x > 20 + 0.60x

x < 700 mi

For less that 700 miles the rental cost for Company A is a better deal.
