The budgeted overhead at the planned volumes at the beginning of November was as follows: Variable overhead $75,600 Fixed overhead 50,400 Total $126,000 The actual factory overhead was $127,500 for November. The actual fixed factory overhead was as budgeted. During November, the Weaving Department had standard hours at actual production volume of 44,000 hours. Determine the variable factory overhead controllable variance and the fixed factory overhead volume variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number. Round your interim computations to the nearest cent, if required. a. Variable factory overhead controllable variance: $ b. Fixed factory overhead volume variance: $
