Answer:
Option (D) is correct.
Explanation:
Calculation of total manufacturing overhead:-
4000 units manufacturing overhead:
= Production volume × Manufacturing overhead
= 4,000 × $94
= $376,000
5000 units manufacturing overhead:
= Production volume × Manufacturing overhead
= 5,000 × $77.60
= $388,000
Variable cost per unit:
[tex]=\frac{5000\ units\ manufacturing\ overhead-4000\ units\ manufacturing\ overhead}{1000}[/tex]
[tex]=\frac{388,000-376,000}{1000}[/tex]
= 12
Fixed cost = Total cost - variable cost
= $388,000 - 5,000 × 12
= $388,000 - $60,000
= $328,000
So total monthly fixed manufacturing cost is $328,000.
