Final answer:
The efficiency variance for variable overhead setup costs is $150 favorable. The spending variance for variable overhead setup costs is $150 unfavorable. The flexible-budget variance for variable overhead setup costs is $37 favorable. The spending variance for fixed overhead setup costs is $250 unfavorable. The production-volume variance for fixed overhead setup costs is $1,800 unfavorable.
Step-by-step explanation:
The efficiency variance for variable overhead setup costs can be calculated by multiplying the actual quantity of setup hours by the budgeted variable overhead rate per setup hour and subtracting it from the actual variable overhead cost. In this case, the actual quantity of setup hours is 5.5, the budgeted variable overhead rate per setup hour is $50, and the actual variable overhead cost is $52. Therefore, the efficiency variance is ($52 - (5.5*$50)) = $150 favorable.
The spending variance for variable overhead setup costs can be calculated by subtracting the budgeted variable overhead cost from the actual variable overhead cost. In this case, the budgeted variable overhead cost is (5.5*$50) = $275, and the actual variable overhead cost is $52. Therefore, the spending variance is ($52 - $275) = $150 unfavorable.
The flexible-budget variance for variable overhead setup costs can be calculated by subtracting the budgeted variable overhead cost from the flexible budget variable overhead cost. In this case, the budgeted variable overhead cost is (5.5*$50) = $275, and the flexible budget variable overhead cost is (6*$52) = $312. Therefore, the flexible-budget variance is ($312 - $275) = $37 favorable.
The spending variance for fixed overhead setup costs can be calculated by subtracting the budgeted fixed overhead cost from the actual fixed overhead cost. In this case, the budgeted fixed overhead cost is $18,000, and the actual fixed overhead cost is $17,750. Therefore, the spending variance is ($17,750 - $18,000) = $250 unfavorable.
The production-volume variance for fixed overhead setup costs can be calculated by multiplying the standard fixed overhead rate per setup hour by the difference between the actual quantity of setup hours and the budgeted quantity of setup hours. In this case, the standard fixed overhead rate per setup hour is ($18,000/6) = $3,000, the actual quantity of setup hours is 5.5, and the budgeted quantity of setup hours is 6. Therefore, the production-volume variance is ($3,000 * (5.5 - 6)) = $1,800 unfavorable.
