Answer:
$45
Step-by-step explanation:
Note that the Heating Division is operating at full capacity. Therefore, satisfying the internal order will result in external orders of 15,000 heating units being forgone.
Minimum Transfer Price = Variable Costs - Internal Savings + Opportunity cost
Where,
Variable Costs = $25
Internal Savings = $0
Opportunity cost = $45 - $25 = $20
Therefore,
Minimum Transfer Price = $25 + $20
= $45
The minimum transfer price that the Heating Division should accept is $45.
