The correct answer is D.
Explanation:
Giving the following information:
Variable manufacturing overhead is applied to products based on direct labor-hours. Variable manufacturing overhead 0.10 hours $ 5.30 per hour.
Actual direct labor-hours 820 hours
Actual variable overhead cost $ 4,592
variable overhead efficiency variance= (SQ - AQ)*SR
variable overhead efficiency variance= (7,600*0.10 - 820)*5.3= $318 unfavorable
