The following data relate to factory overhead cost for the production of 6,000 computers: Actual: Variable factory overhead $173,100 Fixed factory overhead 42,500 Standard: 6,000 hrs. at $34 204,000 If productive capacity of 100% was 10,000 hours and the total factory overhead cost budgeted at the level of 6,000 standard hours was $221,000, determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $4.25 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.
