Question
9. Suppose that the demand equation for a monopolist is p = 100 – 0.01x and the cost function
is C(x) = 50x + 10, 000.
(a) Find the marginal cost.
(b) Find the value of x that maximizes the profit and determine the corresponding price and
total profit for this level of production.
(Answer: Produce 2500 units and sell them at $75 per unit. The profit will be $52,500).
10. The total cost, in dollars, of producing x units of a certain product is given by
C (x) = 8x + 20+
100
and the average cost is defined by A(x) = C(x)/x.
(a) Find A'(x) and C' (x).
(b) Find the minimum of A(x) and the value xo at which it occurs.
(c) Compare A(xo) and C'(xo).
