The Platter Valley factory of Bybee Industries manufactures field boots. The cost of each boot includes direct materials, direct labor, and manufacturing $($factory$)$ overhead. The firm traces all direct costs to products, and it assigns overhead cost to products based on direct labor hours.

The company budgeted $$13,630$ variable factory overhead cost, $$89,300$ for fixed factory overhead cost and $2,350$ direct labor hours $($its practical capacity$)$ to manufacture $4,700$ pairs of boots in March.

The factory used $2,900$ direct labor hours in March to manufacture $4,600$ pairs of boots and spent $$16,000$ on variable overhead during the month. The actual fixed overhead cost incurred for the month was $$91,500.$

The Platter Valley factory of Bybee Industries uses a two$-$variance analysis of the total factory overhead variance.

Required

$1.$ Compute the total flexible$-$budget variance for overhead and the production volume variance for March. What was the total factory overhead cost variance for March? Indicate whether each variance is favorable $($F$)$ or unfavorable $($U$).$

$2.$ Determine the three components of the total flexible$-$budget variance for overhead $($i$.$e$.,$ the variable overhead spending variance, the variable overhead efficiency variance, and the fixed overhead spending variance$)$; in addition, show the production volume variance for March. Indicate whether each variance is favorable $($F$)$ or unfavorable $($U$).$
