Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below $8.00 5.55 2.75 5.25 $21.55 Direct materials-1 pound plastic at $8.00 per pound Direct labor-0.5 hours at $11.10 per hour Variable manufacturing overhead Fixed manufacturing overhead Total standard cost per unit The predetermined manufacturing overhead rate is $16.00 per direct labor hour ($8.00 0.5). It was computed from a master manufacturing overhead budget based on normal production of 2,500 direct labor hours (5,000 units) for the month. The master budget showed total variable costs of $13,750 ($5.50 per hour) and total fixed overhead costs of $26,250 ($10.50 per hour). Actual costs for October in producing 3,900 units were as follows 32,886 19,950 21,838 11,362 $86,036 Direct materials (4,060 pounds) Direct labo (1,750 hours) Variable overhead Fixed overhead Total manufacturing costs The purchasing department buys the quantities of raw materials that are expected to be used in production each month. Raw materials inventories, therefore, can be ignored Compute all of the materials and labor varlances, Compute all of the materials and labor variances.
