Answer:
The total overhead variance is $2,600 unfavorable
Step-by-step explanation:
The computation of the total overhead variance is shown below:
= Fixed overhead cost + variable overhead cost - (produced gallon × direct labor hour × predetermined overhead rate)
= $8,000 + $4,600 - (1,000 × 2 × $5)
= $12,600 - $10,000
= $2,600 unfavorable
Since, standard cost is less than the actual overhead cost, so it has unfavorable variance.
