Answer:
$32,700 Favorable
Explanation:
Variable Manufacturing overhead efficiency variance can be computed as follows,
VMOH Variance = Standard Overhead rate * (Actual Hours - Standard Hours)
VMOH Variance = 6.0 * (2050 - (1500 * 5))
Variance = $32,700 Favorable
This a favorable variance as budgeted per tub direct labor hours are more than they actually were at production level of 1500 tubs.
Hope that helps.
