Problema Solution
A truck can be rented from company A for $80 a day plus $0.30 per mile. Company B charges $60 a day plus $0.40 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost fro company A a better deal than company B?
Answer provided by our tutors
Write the equations for each company. Let x be the number of miles driven.
For Company A, they charge 80 + 0.3x.
For Company B, they charge 60 + 0.4x.
Now set the two companies equal to find when they have the same price. At that point, any miles greater than or less than will change which company has the better deal.
80+ 0.3x = 60 + 0.4x
20 = 0.1x
x = 200
Therefore, at 150 miles, the best deal changes companies
