Driving Costs A study of the costs of driving 2,012 small-sized sedans found that the average cost per mile (car payments, gas, insurance, upkeep, and depreciation), measured in cents per mile, is approximated by the function 2,410 C ( x ) = -" 1.95 + 32.8 where x denotes the number of miles (in thousands) the car is driven in a year.t (a) What is the average cost (in cents per mile) of driving a small-sized sedan the following mi/year? (Round your answers to one decimal place.) 5,000 mi/year cents/mi 10,000 mi/year cents/mi 15,000 mi/year cents/mi 20,000 mi/year cents/mi 25,000 mi/year cents/mi (b) Use part (a) to sketch the graph of the function C. 400 400 300 300 200 200 100 100 5 10 15 20 25 5 10 15 20 25 400 400 300 300 200 200 100 100 5 10 15 20 25 5 10 15 20 25 (c) What happens to the average cost as the number of miles driven increases without bound? It approaches 1.95 cents per mile. It approaches 0 cents per mile. It approaches 2,042.8 cents per mile. It also increases without bound. It approaches 32.8 cents per mile
