Fixed Overhead Spending and Volume Variances, Columnar and Formula Approaches Corey Company provided the following information: Standard fixed overhead rate (SFOR) per direct labor hour $10.00 Actual fixed overhead $425,000 Budgeted fixed overhead $500,000 Actual production in units 8,500 Standard hours allowed for actual units produced (SH) 42,500 Required Enter amounts as positive numbers and select Favorable (F) or Unfavorable(U). If no variance, enter $0 and select 0. 1. Using the columnar approach, calculate the fixed overhead spending and volume variances. (1) Spending Volume 2. Using the formula approach, calculate the fixed overhead spending variance. 3. Using the formula approach, calculate the fixed overhead volume variance. 4. Calculate the total fixed overhead variance
