The following data relate to factory overhead cost for the production of 3,000 computers: If productive capacity of 100% was 5,000 hours and the factory overhead cost budgeted at the level of 3,000 standard hours was exist120,000, determine the variable factory overhead Controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was exist6 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number. Controllable variance Volume variance Total factory overhead cost variance
