The total cost (in dollars) of manufacturing x auto body frames is C(x) = 60,000 + 200x. (A) Find the average cost per unit if 500 frames are produced. [Hint: Recall that C(x) is the average cost per unit] (B) Find the average value of the cost function over the interval [0,500]. (C) Discuss the difference between parts (A) and (B). (A) The average cost per unit if 500 frames are produced is $ (B) The average value of the cost function is $ (C) $ $ $☐ is the average cost per unit at a production level of 500 units. is the average value of the total cost as production increases from 0 to 500 units.
