Answer:
$13,640 Unfavorable
Step-by-step explanation:
Data provided
Actual hours = 2,600
Standard hours = 6.0
Standard variable overhead rate = $12.40
The computation of variable overhead efficiency variance is shown below:-
Variable overhead efficiency variance = (Actual hours - Standard hours) × Standard rate
= (2,600 - (250 × 6.0)) × $12.40
= (2,600 - 1,500) × $12.40
= 1,100 × $12.40
= $13,640 Unfavorable
Therefore for computing variable overhead efficiency variance we simply applied the above formula.
