Kesha is planning to rent a van for her trip Mt. Rainier. Two of her friends each rented the same type
of van from the same car rental company last week. This is what they told her:
John: “The cost of my rental was $240. The company charged me a certain amount per day
and a certain amount per mile. I had the rental for five days and drove it 200 miles.”
Katie: “The cost of my rental was only $100. I drove it for 100 miles and had it for two days.”
Kesha plans to get the same type of van that John and Katie had from the same car rental company.
Kesha estimated her trip would be 250 miles, and she would have the vehicle for four days.
Let C = cost, M = miles, and D = days
Which of the following equations could Kesha use to figure out how much her rental would cost?
a. C = 40.00M + 0.20D
b. C = 40.00D + 0.20M
c. C = 20.00M + 0.40D
d. C = 20.00D + 0.40M
