How would one go about solving for flexible budgets and overhead variance?

Antuan Company set the following standard costs for one unit of its product. Direct materials (4.0 Ibs. @ $5.00 per Ib.) $20.00 Direct labor (1.9 hrs. 6 $13.00 per hr.) 24.70 Overhead (1.9 hrs. 9 $18.50 per hr.) 35.15 Total standard cost $79.85 The predetermined overhead rate ($18.50 per direct labor hour) is based on an expected volume of 75% of the factory's capacity of 20,000 units per month. Following are the company's budgeted overhead costs per month at the 75% capacity level. Overhead Budget (75% Capacity) Variable overhead costs Indirect materials $ 15,000 Indirect labor 75,000 Power 15,000 Repairs and maintenance 30,000 Total variable overhead costs $135,000 Fixed overhead costs DepreciationBuilding 24,000 DepreciationMachinery 70,000 Taxes and insurance 17,000 Supervision 281,250 Total fixed overhead costs 392,250 Total overhead costs $527,250 The company incurred the following actual costs when it operated at 75% of capacity in October. The company incurred the following actual costs when it operated at 75% of capacity in October.

Compute the direct materials cost variance, including its price and quantity variances. A0 = Actual Quantity so = Standard Quantity AP = Actual Price SP = Standard Price 4 . Compute the direct labor cost variance , including its rate and efficiency variances . AH = Actual Hours SH = Standard Hours AR = Actual Rate SR = Standard Rate Actual Cos Standard Cos5. Prepare a detailed overhead variance report that shows the variances for individual items of overhead.
