Claude spends $315 to rent a car. the car he rents costs $45 per day. he has a coupon for 2 free days. complete the equation below to find the number of days claude rents the car. use d to represent the number of days = 2 2 2 2 9 9 9 9 45 45 45 45 90 90 90 90 350 350 350 350 d d d d

He rents for d days, but two days are free, so he pays for only d - 2 days.

The rental fee is $45 per day, so for d - 2 days, he pays 45(d - 2). The total he pays is $315, so the equation is

45(d - 2) = 315

Now we solve the equation to find d, the number of days.

45(d - 2) = 315

45d - 90 = 315

45d = 405

d = 9

The number of days is 9.
