A car rental company at a major airport on an average rents 70 percent of its fleet of 200 cars per day. The cars are rented for an average of 4 days. What is the average number of rentals processed per day?

This is a simple question of percentages and multiplication. You first have to find 70 percent of 200 which is 140. Then you must multiply that by the 4 days which equals 660. That is your answer. It is 660 cars.
