Answer:
$6,000 incremental cost
Explanation:
Manufacturing the widgets in-house would be a more cost effective method than buying from Bowden Company.
Direct Costs relating to in-house manufacturing (of 100,000 units) are as follows:
Direct material = $31,000
Direct labour = $29,000
Manufacturing overhead directly related to the manufacture of the widgets: $16,000.
Therefore, total direct costs = $76,000.
Only the portion of manufacturing overhead directly affected by the widget production needs to be account for. This is because manufacturing overhead will be incurred irrespective of whether Mallory Company produces the widget or not. Therefore, manufacturing overhead is not an incremental cost incurred by the widget production, except for the portion directly affected.
Accordingly, producing in-house ($76,000 direct cost) is more cost effective that buying from Bowden Company ($82,000) by $6,000.
The incremental cost if the widgets are bought instead of made is therefore $6,000.
