Division Delta of Golvin Corporation makes and sells a single product which is used by manufacturers of fork lift trucks. Presently it sells 9,000 units per year to outside customers at $57 per unit. The annual capacity is 10,000 units and the variable cost to make each unit is $32.

There would be no cost savings from transferring the units within the company rather than selling them on the outside market. What should be the lowest acceptable transfer price from the perspective of Division Delta
