A car rental company charges $25 per day plus an additional fee of $0.15 per mile driven. How much would it cost to rent a car for 3 days and drive 200 miles?

To calculate the total cost of renting the car, we need to consider both the daily charge and the mileage charge.

First, let's calculate the cost of renting the car for 3 days:

Daily charge = $25 per day
Total days = 3

Cost for 3 days = Daily charge * Total days
                        = $25 * 3
                        = $75

Next, let's calculate the cost of driving 200 miles at $0.15 per mile:

Mileage charge = $0.15 per mile
Total miles = 200

Cost for 200 miles = Mileage charge * Total miles
                           = $0.15 * 200
                           = $30

Finally, we add the two costs together to find the total cost of renting the car:

Total cost = Cost for 3 days + Cost for 200 miles
                 = $75 + $30
                 = $105

So, it would cost $105 to rent a car for 3 days and drive 200 miles.
