Division A manufactures electronic circuit boards that can be sold to Division B of the same company or to outside customers. Last year, the following activity occurred in Division A: Selling price per circuit board Variable cost per circuit board Number of circuit boards: Produced during the year Sold to outside customers Sold to Division B $ 185 $ 126 20,500 14,600 5,900 Sales to Division B were at the same price as sales to outside customers. The circuit boards purchased by Division B were used in an electronic instrument manufactured by that division (one board per instrument). Division B incurred $220 in additional variable cost per instrument and then sold the instruments for $670 each. Required: 1. Calculate the net operating incomes earned by Division A. Division B, and the company as a whole. 2. Assume Division A's manufacturing capacity is 20,500 circuit boards. Next year, Division B wants to purchase 6,900 circuit boards from Division A rather than 5,900. (Circuit boards of this type are not available from outside sources.) From the standpoint of the company as a whole, should Division A sell the 1,000 additional circuit boards to Division B or continue selling them to outside customers?
