Refer to the information in 15-23. Calculate and label the following overhead variances for the year:
In 15-23, Patel and Sons, Inc., uses a standard cost system to apply overhead costs to units produced. Practical capacity for the plant is defined as 50,000 machine hours per year, which represents 25,000 units of output. Annual budgeted fixed overhead costs are $250,000 and the budgeted variable overhead cost is $4 per unit. Factory overhead costs are applied on the basis of standard machine-hours allowed for units produced. Budgeted and actual output for the year was 20,000 units, which took 41,000 machine hours. Actual fixed overhead costs for the year amounted to $245,000 while the actual variable overhead cost per unit was $3.90. What was?

(a) Total overhead variance,
(b) Total flexible-budget variance,
(c) Production-volume variance.
