The following data relate to factory overhead cost for the production of 3,000 computers:

Actual:	Variable factory overhead	$50,900
	Fixed factory overhead	17,500
Standard:	3,000 hrs. at $21	63,000

If productive capacity of 100% was 5,000 hours and the total factory overhead cost budgeted at the level of 3,000 standard hours was $70,000, determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $3.5 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.
