Leung Corporation manufactures a single product. The standard cost per unit of product is as follows. The master manufacturing overhead budget for the month based on normal productive capacity of 20,000 direct labor hours ( 10,000 units) shows total variable costs of $80,000 ( $4 per labor hour) and total fixed costs of $60,000 ( $3 per labor hour). Normal productive capacity is 20,000 direct labor hours. Overhead is applied on the basis of direct labor hours. Actual costs for November in producing 9,800 units were as follows. The purchasing department normally buys the quantities of raw materials that are expected to be used in production each month. Raw materials inventories, therefore, can be ignored. (1) Compute (a) total material variance, (b) price variance, and (c) quantity variance (show calculations with formula) (2) Compute (a) total labor variance, (b) labor price variance, (c) labor quantity variance (show calculations with formula) [Note: For this math, students must show the calculation to get points. Only writing/providing answers will not be graded]
