B. Kiwan Inc. has the cost function C(Q) = 1000 + 1000 + 1002, where Q: the quantity of output produced. (1) Write expressions for Average Fixed Cost (AFC), Average Variable Cost (AVG). Average Total Cost (ATC), and Marginal Cost (MC). (2) a. Graph the four cost functions found in (1). b. Indicate the firm's short-run supply curve on the graph. G. Write down the formula for the inverse supply curve. d. At what price is the firm indifferent between shutting down and staying open in the short run? (3) Solve for the quantity that minimizes ATC using one of the two possible methods; then check answer using the other method. (4) a. Write down an expression for Kiwan's profit function. Then derive the formula for the quantity that will maximize the profit function (i.e. q*= q(p), where p = unit price). b. Graph the profit function for Kiwan if the unit price of O is $500. Then graph the profit function if the unit price of Q is $100. Be sure the important points of the functions are illustrated, i.e. the maximum point and points of zero profit
