Quizplus · Accepted Answer

Variable component of the predetermined overhead rate (SR) = $29,125/12,500 machine-hours
= $2.33 per machine-hour
Variable overhead efficiency variance = (AH - SH) × SR
= (10,400 machine-hours - 11,000 machine-hours) × $2.33 per machine-hour
= (-600 machine-hours) × $2.33 per machine-hour
= $1,398 F
