BOOKMARK
The total cost of renting a car is determined by the number of days a car is rented, at $75 per day, and the number of miles it is driven, at $0.50 per mile. The company uses the expression 75x +0.50y to evaluate the total cost of renting a car. What does the variable x represent?
the total amount charged per rental day
the total number of miles driven
the total number of days rented
D the total amount charged per mile driven

Answer 1

In the car rental cost expression 75x + 0.50y, the variable x represents the total number of days the car is rented.

Step-by-step explanation:

In the expression 75x + 0.50y that the car rental company uses to calculate the total cost of renting a car, the variable x represents the total number of days rented.

This can be determined by understanding that the total cost is composed of a daily rate and a mileage rate. Since $75 is multiplied by x, and the cost per day is $75, then x must represent the number of days the car is rented.

In contrast, y represents the total number of miles driven since it is multiplied by the per mile charge of $0.50.
