1. Ajax Division of Carlyle Corporation produces electric motors, 20% of which are sold to Bradley Division of Carlyle and the remainer to outside customers. Carlyle treats ist divisions as profit centers and allows division managers to choose their sources of sales and supply. Corporate policy requires that all interdivisional sales and purchases be recorded at variable cost as a transfer price. Ajax Division's estimated sales and standard cost data for the year ending December 31, 2013 based on the full capacity of 100,000 units, are as follows: Ajax has an opportunity to sell the above 20,000 units to an outside customer at a price of $75 per unit during 2013 on a continuing basis. Bradley can purchase its requirements from an outsider supplier at a price of $85 per unit. Assuming that Carlyle desires to maximize its gross margin, should Ajax Division take on the new customer and drop its sales to Bradley for 2013, and why ?
