A) $5,400 Favorable 
B) $5,472 Unfavorable 
C) $21,600 Unfavorable 
D) $51,000 Unfavorable

Quizplus · Accepted Answer

SR = $410,400 ÷ 7,600 hours = $54 per hour
Variable overhead efficiency variance = (AH − SH) × SR
= (7,500 hours - 7,600 hours) × $54 per hour
= (-100 hours) × $54 per hour
= $5,400 F
