Answer:
a. Variable factory overhead controllable variance: $3,200 F
b. Fixed factory overhead volume variance: $3,710 F
Step-by-step explanation:
a)
Standard rate of variable overhead = (variable overhead)/(Production hours)
Standard rate of variable overhead = $108,000 / 40000 = $2.70 per hour
Standard hours for actual production = 42000 hours
Budgeted variable overhead for actual production = (standard hours of production* standard rate of variable overhead)
Budgeted variable overhead for actual production = 42000 * $2.70 = $113,400
Actual factory overhead = $184,400
Fixed overhead = $74,200
Actual variable overhead incurred = (Actual factory overhead) - (Fixed overhead)
Actual variable overhead incurred = $184,400 - $74,200 =$110,200
Variable factory overhead controllable variance = Budgeted variable overhead for actual production - Actual variable overhead
Variable factory overhead controllable variance = $113,400 - $110,200
Variable factory overhead controllable variance = $3,200 F
b)
Budgeted fixed overhead = $74,200
Predetermined fixed overhead rate = $74200 / 40000 = $1.855 per hour
Fixed overhead applied = Standard hours for actual production * Overhead rate = 42000 * $1.855 = $77,910
Fixed factory overhead volume variance = Fixed overhead applied - Budgeted fixed overhead
= $77910 - $74200= $3,710 F
