Rogen Corporation manufactures a single product. The standard cost per unit of product is shown belovw Direct materials-1 pound plastic at $8 per pound Direct labor-1.00 hours at $11.90 per hour Variable manufacturing overhead Fixed manufacturing overhead $ 8.00 11.90 5.50 10.50 $35.90 Total standard cost per unit The predetermined manufacturing overhead rate is $16 per direct labor hour ($16.00 1.00). It was computed from a master manufacturing overhead budget based on normal production of 5,600 direct labor hours (5,600 units) for the month. The master budget showed total variable costs of $30,800 ($5.50 per hour) and total fixed overhead costs of $58,800 ($10.50 per hour). Actual costs for October in producing 4,300 units were as follows Direct materials (4,400 pounds) Direct labor (4,160 hours) Variable overhead Fixed overhead $36,080 50,752 49,534 21,066 $157,432 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 variances. (Round answers to 0 decimal places, e.g. 125.)
