Factory Overhead Cost Variances

The following data relate to factory overhead cost for the production of 8,000 computers:

Actual:	Variable factory overhead	$188,200
	Fixed factory overhead	61,750
Standard:	8,000 hrs. at $29	232,000

If productive capacity of 100% was 13,000 hours and the total factory overhead cost budgeted at the level of 8,000 standard hours was $255,750, determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $4.75 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.
