Question

10) A car rental company charges $80 to rent a car, plus .20 per mile. They also offer their customers the option of buying insurance for a flat fee of an additional $40. Which function can be used to calculate the total cost of renting a car for a customer who decides to buy the optional insurance?

Answer 1

Car rent : $80

Cost per mile : $20

Additional insurance : $40

mile = x

To calculate the total cost (y) of renting a car for a customer who decides to buy the optional insurence, we have to add the fixed cost of the Car rental (80) and the cost of the insurance (40), plus the product ot the cost per mile (20) and the number of miles.

y= 80+40+20x

y= 120+20x
