OH variances The manager of the Texas Department of Transportation has determined that it typically takes 30 minutes for the department's employees to register a new car. In Bexar County, the predetermined fixed overhead rate was computed on an estimated 4,000 direct labor hours per month and is $9 per direct labor hour, whereas the predetermined variable overhead rate is $3 per direct labor hour. During July, 7,520 cars were registered in Bexar County, and 3,800 direct labor hours were worked in registering those vehicles. For the month, variable overhead was $11,080 and fixed overhead was $36,320. Note: In answering the following questions, do not use negative signs with your answers. a. Compute overhead variances using a four-variance approach. VOH Spending Variance Actual VOH Budgeted VOH = VOH Spending Variance $ 0 $ 0 = $ 0 VOH Efficiency Variance Budgeted VOH - Applied VOH = VOH Efficiency Variance $ 0-$ 0 $ 0 FOH Spending Variance Actual FOH Budgeted FOH = FOH Spending Variance $ 0 $ 0 = FOH Volume Variance Budgeted FOH - Applied FOH = FOH Volume Variance 0-$ 0 = $ 0 0 b. Compute overhead variances using a three-variance approach. OH Spending Variance Budget at Actual = OH Spending Variance Actual OH $ 0 $ 0 OH Efficiency Variance Budget at Actual - Budget at Standard = OH Efficiency Variance $ 0 S Volume Variance Budget at Standard Applied OH = Volume Variance $ 0 $ 0 $ 0 c. Compute overhead variances using a two-variance approach. Budget Variance -Budgeted OH = Budget Variance Actual OH $ 0 $ 0 = $ 0 Volume Variance Applied OH = Volume Variance Budgeted OH $ 0 $ 0 $ Please answer all parts of the question. 0
