Answer:
a. Controllable Variance = 3,800 (Favorable)
b. Volume Variance = 21,600 (Unfavorable)
Step-by-step explanation:
a. Controllable Variance
Actual variable factory Overhead( 251,800 - 102,600) 149,200
Standard Variable factory Overhead at actual Production
Standard Hours at actual Production (A) 45,000
Variable Factory overhead Rate (B) 3.4
(146,200/ 43,000)
Standard variable factory Overhead (A*B) 153,000
Controllable Variance 3,800 F
b. Fixed factory Overhead volume variance
Volume variance:
Volume at 100% of normal capacity 57,000
Less: Standard hours 45,000
12,000
Fixed Overhead rate (B) (102,600/ 57,000) 1.8
Volume Variance (A*B) 21,600 (Unfavorable)
