Answer:
Variable overhead efficiency variance= $7,000 favorable
Explanation:
Giving the following information:
Actual units produced: 9,000
Actual machine hours worked: 16,000
Standard variable overhead cost per machine hour: $3.50
Standard hours= 2 hours per unit
To calculate the variable overhead efficiency variance, we need to use the following formula:
Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Standard quantity= 2*9,000= 18,000
Variable overhead efficiency variance= (18,000 - 16,000)*3.5
Variable overhead efficiency variance= $7,000 favora
