Answer:
a. $ 32
Explanation:
Computation of purchase price
The company can make the components with a variable cost which is as follows:
Direct Materials per unit $ 12
Direct Labour per unit $ 8
Variable Manufacturing overhead per unit $ 12
Total Variable Cost per unit $ 32
Since the fixed manufacturing overhead shall not be reduced, the maximum price that can be paid is the internal variable costs.
So the maximum purchase price is $ 32
