A company determined that the marginal cost, C'(x) of producing the xth unit of a product is given by C'(x) = x4 6x. Find the total cost function C, assuming that C(x) is in dollars and that xed costs are $5000. 60:) = A company nds that the rate at which the quantity of a product that consumers demand changes with respect to price is given by the marginal-demand function 5000 x2 where x is the price per unit, in dollars. Find the demand function if it is known that 1004 units of the product are demanded by consumers when the price is $5 per unit. D'(x) = E> D(x) = D
