The following data relate to factory overhead cost for the production of 10,000 computers: Actual: Variable factory overhead $262,000 Fixed factory overhead 90,000 Standard: 14,000 hrs. at $25 350,000 If productive capacity of 100% was 15,000 hours and the total factory overhead cost budgeted at the level of 14,000 standard hours was $356,000, determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $6.00 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.
