can anyone help me out with this question...

E21.16 (LO 4), AP Crede Inc. has two divisions. Division A makes and sells student desks. Division B manufactures and sells reading lamps. Each desk has a reading lamp as one of its components. Division A can prchase reading lamps at a cost of $10 from an outside vendor. Division A needs 10,000 lamps for the coming year. Division B has the capacity to manufacture 50,000 lamps annually. Sales to outside customers are estimated at 40,000 lamps for the next year. Reading lamps are sold at $12 each. Variable costs are $7 per lamp and include $1 of variable sales costs that are not incurred if lamps are sold internally to Division A. The total amount of fixed costs for Division B is $80,000. Instructions Consider the following independent situations. a. What should be the minimum transfer price accepted by Division B for the 10,000 lamps and the maximum transfer price paid by Division A? Justify your answer. b. Suppose Division B could use the excess capacity to produce and sell externally 15,000 units of a new product at a unit selling price of $7. The unit variable cost for this new product is $5. What should be the minimum transfer price accepted by Division B for the 10,000 lamps and the maximum transfer price paid by Division A? Justify your answer. c. If Division A needs 15,000 lamps instead of 10,000 during the next year, what should be the minimum transfer price accepted by Division B and the maximum transfer price paid by A? Justify your answer. (CGA adapted)
