Problema Solution
A truck can be rented from Company A for $160 a day plus $0.40 per mile. Company B charges $80 a day plus $0.60 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost for Company A less than the rental cost of Company B?
Answer provided by our tutors
Let the variable 'x' represent the distance in miles.
Company A rental cost = 140 + 0.40x
Company B rental cost = 80 + 0.60x
We can write the question as an inequality with Company A rental cost on the left hand side and Company B rental cost on the right hand side:
160 + 0.4x < 80 + 0.60x

x > 400
More than 400 miles should be driven per day to make the rental cost of Company A less than the rental cost of Company B.
