Quizplus · Accepted Answer

Variable component of the predetermined overhead rate (SR) = $153,425/47,500 machine-hours
= $3.23 per machine-hour
Variable overhead efficiency variance = (AH - SH) × SR
= (42,800 machine-hours - 43,700 machine-hours) × $3.23 per machine-hour
= (-900 machine-hours) × $3.23 per machine-hour
= $2,907 F
