Answer:
$27,600 unfavorable
Step-by-step explanation:
In order to calculated labor efficiency variance which is standard cost of actual hours less standard cost, first compute standard rate as shown below:
Unfavorable direct labor rate variance = $17,800
Unfavorable direct labor rate variance = Actual rate - standard rate × Actual hours
Actual rate = Total payroll for direct labor ÷ Direct labor hours (AQ)
= 427,200 ÷ 35,600
= $12 per unit
Substituting the values in the above formula:
17,800 = (12 - SR) × 35,600
SR = $11.5
Now calculate Standard cost of actual hours = Direct labor hours × SR
= 35,600 × 11.5
= $409,400
Standard cost = Standard direct hours × SR
= 38,000 × 11.5
= $437,000
Direct labor efficiency variance = Standard actual of actual hours - Standard cost
= 409,400 - 437,000
= - $27,600 or $27,600 unfavorable
