Can you please help me with the calculations for the three variances in this equation? Factory Overhead Cost Variances The following data relate to factory overhead cost for the production of 8,000 computers: Actual: Variable factory overhead $217,300 Fixed factory overhead 91,000 Standard: 8,000 hrs. at $35.00 280,000 If productive capacity of 100% was 13,000 hours and the factory overhead cost budgeted at the level of 8,000 standard hours was $315,000, determine the variable factory overhead Controllable Variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $7.00 per hour. Use the minus sign to enter favorable variances as negative numbers. Controllable variance: Volume Variance: Total Factory Overhead Cost Variance.
