Question

20. + 0/4 points Previous Answers My Notes The management of Thermo Master Company, whose Mexican subsidiary manufactures an indoor-outdoor thermometer, has estimated that the total weekly cost (in dollars) for producing x thermometers is represented by the following function. C(x) = 2200 + 2x (a) Find the average cost function C. C(x) = (b) Find the marginal average cost function C'. C'(x) = (c) Interpret your results. Since the marginal average cost function is negative for x > 0, the rate of change of the average cost function is positive for all x > 0. Since the marginal average cost function is negative for x > 0, the rate of change of the average cost function is negative for all x > 0. O Since the marginal average cost function is positive for x > 0, the rate of change of the average cost function is positive for all x > 0. Since the marginal average cost function is positive for x > 0, the rate of change of the average cost function is negative for all x > 0.
