Materials used by the Instrument Division of Dart Industries are currently purchased from outside suppliers at a cost of $180 per unit. However, the same materials are available from the Components Division. The Components Division has unused capacity and can produce the materials needed by the Instrument Division at a variable cost of $125 per unit.

Assume that a transfer price of $158 has been established and that 40,000 units of materials are transferred, with no reduction in the Components Division's current sales.
