Answer:
Variable overhead efficiency variance= $15,200 unfavorable
Step-by-step explanation:
Giving the following information:
Standard hours per unit of output 3.5 hours
Standard variable overhead rate $15.20 per hour
Actual hours 3,800hours
Actual total variable manufacturing overhead cost $59,090
Actual output 800units
To calculate the variable overhead efficiency variance, we need to use the following formula:
Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Variable overhead efficiency variance= (3.5*800 - 3,800)*15.2
Variable overhead efficiency variance= $15,200 unfavorable
