Question

Mr. Smith wants to rent a car but is not sure how long he is going to need it.The rental car company he finds charges a $50.00 fee and then they also add on a $0.15 per mile charge for driving it. Write an expression to represent the cost of renting a car for any number of weeks.

Answer 1

total cost = 50 + 0.15 * x

Explanation:

We have a fixed charge and a variable charge, which would be the number of miles you travel with the car. Therefore, the expression that represents this, would be the following:

x = is the number of miles traveled in a given period

total charge = 50 + 0.15 * x

This total charge corresponds to the cost of renting a car in any amount of time (weeks)
