Stuck on this problem for a while now!

Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below. Direct materialsil pound plastic at $8.00 per pound $ 8.00 Direct labor71.0 hours at $11.30 per hour 11.30 Variable manufacturing overhead 7.00 Fixed manufacturing overhead 7.00 Total standard cost per unit $33.30 The predetermined manufacturing overhead rate is $14.00 per direct labor hour (9;; 14.00 % 1.0). It was computed from a master manufacturing overhead budget based on normal production of 5.400 direct labor hours (5,400 units) for the month. The master budget showed total variable costs of $37300 ($7.00 per hour) and total xed overhead costs of $37,800 ($7.00 per hour).Actua costs for October in producing 3,000 units were as follows. Direct materials (3,120 pounds) $ 25.272 Direct labor (2.350 hours) 32.775 Variable overhead 31.918 Fixed overhead 12.182 Total manufacturing costs $102,147 The pu rchasing department buys the quantities of raw materials that are expected to be used in production each month. Raw materials inventories, therefore. can be ignored. (a) Compute all of the materials and labor variances. Total materials variance Materials price variance Materials quantity variance Total labor variance Labor price variance Labor quantity variance $ (b) Compute the total overhead variance.
