Russell Preston delivers parts for several local auto parts stores. He charges clients 0.85 per mile driven. Russell has determined that if he drives 3,000 miles in a month, his average operating cost is $0.75 per mile. If he drives 5,000 miles in a month, his average operating cost is $0.55 per mile.
