Answer:
$270,000
Explanation:
The computation of the total overhead cost is shown below:
= Variable manufacturing overhead cost + fixed manufacturing overhead cost
where,
Variable manufacturing overhead cost is
= $90,000 ÷ 15,000 hours × 25,000 hours
= $150,000
And, the fixed manufacturing overhead is $120,000
So, the total overhead cost is
= $150,000 + $120,000
= $270,000
