Answer:
-$4,080 favorable
Step-by-step explanation:
The computation of the variable factory overhead controllable variance is shown below:
Standard labour overheads needed for actual output
= 6,600 units × 7 direct labor hours
= 46,200
Standard overhead cost = 2.60 × 46,200 hours
= $120,120
And, Actual overhead cost is $116,040
Now the Variance is
= standard overhead cost - actual overhead cost
= $120,120 - $116,040
= -$4,080 favorable
