If C(x) is the cost of producing x units of a commodity, then the average cost per unit is c(x) = C(x)/x. The marginal cost is the rate of change of the cost with respect to the number of items produced, that is, the derivative C'(x). (a) Show that if the average cost is a minimum, then the marginal cost equals the average cost. (b) If C(x) = 16,000 + 200x + 4x³/², in dollars, find (i) the cost, average cost, and marginal cost at a produc- tion level of 1000 units; (ii) the production level that will minimize the average cost; and (iii) the minimum average cost.
