Answer:
Minimum transfer price = $86
Explanation:
Pump Division is operating at full capacity, hence it has no excess capacity
This implies that it can not produce enough to meet both the internal demand (from the Pool Division ) and external buyers.
Hence, it implies that Pump Division cannot accommodate the demands of the Pump Division at a price lower than the external price of $86. Any price lower than $86 would result into a loss in contribution.
To maximize and optimize the group profit, the minimum transfer price should be set as follows:
Minimum transfer price = External selling price at which Pump Division sells to outside customers
Minimum transfer price = $86
