Santa Fe Company has two divisions in Kansas, Holton Division and Derby Division. Currently, Derby buys a part (10,000 units) from Holton for $16 per unit. Holton has purchased new equipment and wants to increase the price to Derby to $18 per unit. The controller of Derby claims that she cannot afford to go that high, as it will decrease the division's profit to near zero. Derby can buy the part from an outside supplier for $16 per unit. The incremental costs per unit that Santa Fe incurs to produce each unit are Holton's variable costs of $12. Fixed costs per unit for Holton with recent purchase of equipment are $5. 2.
