Smithson Company manufactures shirts. During June. Smithson made 1, 100 shirts but had budgeted production at 1300 shirts. Smithson gathered the following additional data: Calculate the following variances: Variable overhead cost variance Variable overhead efficiency variance Total variable overhead variance Fixed overhead cost variance Fixed overhead volume variance Total fixed overhead variance Calculate the variable overhead cost variance. Select the formula, then enter the amounts and compute the cost variance for variable overhead (VOH) and identify whether the variance is favorable (F) or unfavorable (U Calculate the variable overhead efficiency variance. Select the formula, then enter the amounts and compute the efficiency variance for variable overhead and identify whether the variance is favorable (F) or unfavorable (U). Calculate the total variable overhead variance The total variable overhead variance is Calculate the fixed overhead cost variance Select the formula, then enter the amounts and compute the cost variance for fixed overhead (FOH) and identify whether the variance is favorable (F) or unfavorable (U). Calculate the fixed overhead volume variance First, select the formula, then enter the amounts and compute the fixed overhead allocated to production. Now, select the formula, then enter the amounts and compute the fixed overhead volume variance and identify whether the variance is favorable (F) or unfavorable (U). Calculate the total fixed overhead variance. The total fixed overhead variance is
