Answer:
a) $12,500 unfavorable
b) 0
Explanation:
variable factory overhead controllable variance = actual variable overhead expense - (standard variable overhead per unit x standard number of units)
actual variable overhead expense = $725,000
standard variable overhead per unit = $712,500 / 60,000 = $11.875
standard number of units = 60,000
variable factory overhead controllable variance = $725,000 - $712,500 = $12,500 unfavorable
Controllable factory overhead is not related to any changes in the actual volume or quantity produced.
Fixed factory overhead volume variance = actual fixed overhead - standard fixed overhead = $262,500 - $262,500 = 0
Fixed overhead was exactly the same as the standard or budgeted overhead.
