The Molding Division of Cotwold Company manufactures a plastic casing used by the Assembly Division. This casing is also sold to external customers for $44 per unit. Variable costs for the casing are $12 per unit and fixed cost is $6 per unit. Cotwold executives would like for the Molding Division to transfer 27,000 units to the Assembly Division at a price of $38 per unit. Assume that the Molding Department has excess capacity, but the Assembly Department requires the casing to be made from a specific blend of plastics. This would raise the variable cost per unit to $42
