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 , so does this mean he can rent the car for at least 6 days or no more than 6 days?
no more than 6 days.
He can afford to rent the car for less than or equal to 6 days.
To solve the inequality 60d + 40 <= 400, we need to isolate the variable d, which represents the number of days Michael can rent the car.
First, subtract 40 from both sides of the inequality:
60d + 40 - 40 <= 400 - 40
This simplifies to:
60d <= 360
Next, divide both sides of the inequality by 60 to solve for d:
(60d) / 60 <= 360 / 60
This simplifies to:
d <= 6
Therefore, the solution to the inequality is d <= 6. This means that Michael can rent the car for no more than 6 days in order to stay within his budget of $400.
