Division X has asked Division K of the same company to supply it with 6,500 units of part L433 this year to use in one of its products. Division X has received a bid from an outside supplier for the parts at a price of $27.00 per unit. Division K has the capacity to produce 30,000 units of part L433 per year. Division K expects to sell 27,000 units of part L433 to outside customers this year at a price of $32.00 per unit. To fill the order from Division X, Division K would have to cut back its sales to outside customers. Division K produces part L433 at a variable cost of $21.50 per unit. The cost of packing and shipping the parts for outside customers is $2.50 per unit. These packing and shipping costs would not have to be incurred on sales of the parts to Division X. Required: a. What is the range of transfer prices within which both the Divisions' profits would increase as a result of agreeing to the transfer of 6,500 parts this year from Division X to Division K? b. Is it in the best interests of the overall company for this transfer to take place? Explain.
