The Vega Division of Ace Company makes wheels which can either be sold to outside customers or transferred to the Walsh Division of Ace Company. Last month the Walsh Division bought all 4,000 of its wheels from the Vega Division for RM42 each. The following data are available from last month's operations for the Vega Company:

Capacity 12,000 wheel

Selling price per wheel to outside customer RM45

Variable cost per wheel when sold to outside customer RM30

If the Vega Division sells wheels to the Walsh Division, Vega can avoid RM2 per wheel in sales commissions. An outside supplier has offered to supply wheels to the Walsh Division for RM41 each.

Suppose that the Vega Division has ample idle capacity so that transfers to the Walsh Division would not cut into its sales to outside customers. What should be the lowest acceptable transfer price from the perspective of the Vega Division?
