Question #N986
A group of friends is planning a trip. They decide to rent a car for the trip. The cost to rent a car is a flat fee of $25, plus $15 per day. Let *c* represent the total cost, in dollars, and *d* represent the number of days the car is rented. Which of the following equations represents the relationship between *c* and *d*?
A. c = 25d + 15
B. c = 15d + 25
C. c = 25 + 15d
D. c = 15 + 25d
Correct Answer is: B
The flat fee of $25 is a constant cost, and the cost per day, $15, is multiplied by the number of days, *d*. Therefore, the total cost, *c*, is represented by the equation c = 15d + 25.
