Answer:
Lost contribution per unit = $56 per unit
Explanation:
The Division X is operating at less than full capacity, hence it has excess capacity of 600 units i.e (5000- 4,400)
This implies that it can only produce to meet the external and a portion of Division Y demand
Since Division X can only accommodate a portion of the internal demand, an opportunity would arise if it decides to meet all the request of Division Y.
Therefore, the minimum transfer price
minimum transfer price= Variable cost + a lost contribution from internal supply
The lost contribution represent the amount Division X would have made had sold the units to external buyers
Lost contribution per unit = $56 per unit
