Question

Michael wants to rent a car on his vacation. The rental fee is 60 dollars per day plus a refueling charge of $40. He has at most 400.00 to spend. The inequality 60d +40 <= 400 can be used to find d, the number of days he can rent the car. Solve the inequality and interpret the solution. I got

d <=6 ,  no more than 6 days, then if he upgraded to a car with a daily rental of 75.00 dollars ...75d +40 <=400
I got:
d <= 4.8

so is the answer he can rent the car for 4 or less days?

sorry and thank you so much
