Marginal cost Suppose that the total cost (in dollan for a product is given by C(x) 1500 + 200 In (2x + 1) where x is the number of units produced. (a) Find the marginal cost function.itapro (b) Find the marginal cost when 200 units are duced, and interpret your result. (c) Total cost functions always increase h must ducing more items costs moreWaoes it ap true of the marginal cost function? I this problem? What then 44.
