Answer:
B. $270,000.
Explanation:
The computation of the total overhead cost is shown below:
But before that first we have to find out the variable overhead per hour which is
= $90,000 ÷ 15,000
= $6 per hour
Now
Variable overhead for 25,000 hours is
= $6 per hour × 25,000
= $150,000
So,
Total overhead cost is
= Variable overhead for 25,000 hours + Fixed overhead cost
= $150,000 + $120,000
= $270,000
hence, the correct option is B. $270,000
