Factory Overhead Cost Variances

The following data relate to factory overhead cost for the production of 4,000 computers:

Actual:	Variable factory overhead	$96,000
	Fixed factory overhead	37,500
Standard:	4,000 hrs. at $31	124,000

If productive capacity of 100% was 6,000 hours and the total factory overhead cost budgeted at the level of 4,000 standard hours was $136,500, determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $6.25 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.
