The total cost (in hundreds of dollars) to produce x units of perfume is C(x)=5x+97x1. (a) Find the average cost function. (b) Find the marginal average cost function. (c) Find the average cost and the marginal average cost for a production level of 35 units. Interpret your results. (a) The average cost function is C(x)= (b) The marginal average cost function is c(x)= (c) The average cost for 35 units is $ per unit. The marginal average cost for 35 units is 3 (Round to the nearest cent as needed.) Interpret your results. When 35 units are produced, the average cost is $ per unit and the average cost is (Round to the nearest cent as needed.)
