Variable Overhead Spending and Efficiency Variances, Columnar and Formula Approaches Aretha Company provided the following information: Standard variable overhead rate (SVOR) per direct labor hour $4.70 Actual variable overhead costs $335,750 Actual direct labor hours worked (AH) 69,200 Actual production in units 14,000 70,000 Standard hours (SH) allowed for actual units produced Required: 1. Using the columnar approach, calculate the variable overhead spending and efficiency variances. Enter amounts as positive numbers and select Favorable (F) or Unfavorable (U). (1) AH X SVOR SH X SVOR Spending Efficiency Efficiency variance 2. Using the formula approach, calculate the variable overhead spending variance. Enter amount as a positive number and select Favorable or Unfavorable. 3. Using the formula approach, calculate the variable overhead efficiency variance. Enter amount as a positive number and select Favorable or Unfavorable. 4. Calculate the total variable overhead variance. Enter amount as a positive number and select Favorable or Unfavorable
