Answer:
Fixed overhead volume variance =$3,875 adverse
Step-by-step explanation:
The non-controllable variance is the fixed overhead volume variance. It is the sum of the fixed overhead efficiency variance and the fixed overhead capacity variance
The efficiency variance is the difference between the standard hours of actual production and the actual hours multiplied by the fixed overhead absorption rate
Capacity variance is the difference budgeted hours and actual hours multiplied by the Fixed overhead absorption rate
Efficiency variance $
4500 units should have taken (4500×2.50) 11,250
but did take 10,000
variance in hours 1250
Standard Fixed overhead absorption rate× $3.10
Efficiency variance 3,875 favorable
capacity variance $
Budgeted hours (38750/3.10) 12,500
Actual hours 10,000
Variance 2,500 adverse
Standard rate × $3.10
Capacity variance 7,750 adverse
Volume variance = 7750 adverse + 3,875 favorable =$3875 adverse
Fixed overhead volume variance =$3,875 adverse
