Question

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? *

Answer 1

X=number of days rented and in this case you can’t rent for a negative amount of days, so X>1 or X=0

Answer 2

Answer:

Given: 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.

To check: We need to check what does the variable x represent.

Here, the company uses the expression $75x +0.50y$ to evaluate the total cost of renting a car.

Here 75 represents the rent per day, and 0.50 represents the cost per mile.

As, x is multiplied by 75. So, the variable x represents the number of day one has taken the car.
