Answer:
$1,728 U
Explanation:
Budgeted Production = 3500 poles
Actual production = 3800 poles
Standard machine hour/pole= 4.60
Total standard hours for actual production = 3800*4.60 = 17,480 machine hours
Actual machine hours for the month = 17,800 machine hours
Standard variable manufacturing overhead rate = $5.40 per machine hour
The actual variable manufacturing overhead cost = $96,712
Variable overheard Efficiency variance = (Standard overhead rate* (Actual hours - Standard hours)
= $5.40* (17,800- 17,480)
= $5.40 *320
= $1,728 U
The actual hours is more than standard hours. thus, it is an unfavorable variance.
