Answer:
b. $2,500 unfavorable
Explanation:
In the factory overhead controllable variance, only the variable cost is considered that means the fixed cost is not considered and hence, not taken in the computation part.
The computation of the factory overhead controllable variance is shown below:
= Standard factory overhead - variable factory overhead
= 25,000 hours × $8 - $202,500
= $200,000 - $202,500
= - $2,500 or unfavorable
