Problem 23-1A Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below. $5.00 5.50 Direct materials -1 pound plastica 55 per pound Direct labor -0.50 hours at $11.00 per hour Variable manufacturing overhead wed manufacturing overhead Total standard cost per unit The predetermined manufacturing overhead rate is $10 per direct laborur (55.00 +0.50). 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 (S5.50 per hour) and total fixed overhead costs of $11,250 ($4.50 per hour). Actual costs for October in producing 3.000 units were as follows Direct materials (3,100 pounds) Direct labor (1,400 hours) Variable overhead Fixed overhead Total manufacturing costs $18.910 15.680 10,490 $51,390 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, 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 variances.
