Zepol Company is planning to produce 600,000 power drills for the coming year. The company uses direct labor hours to assign overhead to products. Each drill requires 0.75 standard hour of labor for completion. The total budgeted overhead was $1,777,500. The total fixed overhead budgeted for the coming year is $832,500. Predetermined overhead rates are calculated using expected production, measured in direct labor hours. Actual results for the year are:

Actual Production (units)	592,000	Actual variable overhead	$928,000
Actual direct labor hours	446,000	Actual fixed overhead	$935,600

Required:

1. Compute the applied fixed overhead.
2. Compute the fixed overhead spending and volume variances.
3. Compute the applied variable overhead.
4. Compute the variable overhead spending and efficiency variances.
