Rent-a-Car company charges for renting a car $35 plus $15 per day (unlimited mileage).
Ley x denote numer of days and y - denote the total cost of car rental.
Write the equation that expresses y (in dollars) in terms of x (days of rental).
y = 35 + 15 x
To find the equation that expresses the total cost of car rental in terms of the number of days, we first need to identify the fixed cost and the variable cost. In this case, the fixed cost is $35, which is charged regardless of the number of days, and the variable cost is $15 per day.
The equation for the total cost (y) in terms of the number of days (x) can be written as follows:
y = 35 + 15x
In this equation, the fixed cost of $35 is added to the variable cost of $15 multiplied by the number of days (x). This equation gives us the total cost of car rental (y) based on the number of days (x).
