Answer:
B. $12,000
Explanation:
The computation of the fixed manufacturing cost is shown below:
= Number of units × Fixed manufacturing overhead per unit
= 4,000 units × $3
= $12,000
The fixed manufacturing cost for the 5,000 units would remain the same as fixed costs do not change with the production level, it remains fixed. Â
The remaining item is not relevant. Hence, it is ignored.
