Answer 1

The cost of making the component that should be compared to the price of buying it is $15.39 per unit.

Step-by-step explanation:

When deciding whether to make or buy a component, the cost of making the component that should be compared to the price of buying it is the total cost per unit of making the component.

In this case, the unit product cost of the component according to the company's cost accounting system is $16.20. However, we need to consider that 30% of the fixed manufacturing overhead is avoidable if the component is bought from an outside supplier. Thus, the avoidable fixed manufacturing overhead per unit of the component is $2.70 × 30% = $0.81.

Therefore, the cost of making the component that should be compared to the price of buying it is $16.20 - $0.81 = $15.39 per unit.
