Answer:
$17,688 unfavorable
Explanation:
The computation of the variable efficiency variance is shown below:
Variable efficiency variance = (Actual hours - standard hours) × standard rate
= (2,700 hours - 200 units × 6.8 hours) × $13.20
= (2,700 hours - 1,360 hours) × $13.20
= 1,340 hours × $13.20
= $17,688 unfavorable
Since the actual hours is more than the standard hours so it would leads to unfavorable variance
