Direct Materials, Direct Labor, and Factory Overhead Cost Variance Analysis

Mackinaw Inc. processes a base chemical into plastic. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of 7,200 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	9,400 lb. at $4.90		9,300 lb. at $4.80
Direct labor	1,800 hrs. at $17.10		1,840 hrs. at $17.30
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 1,880 direct
	labor hrs.:
		Variable cost, $4.00	$7,130 variable cost
		Fixed cost, $6.30	$11,844 fixed cost

Each unit requires 0.25 hour of direct labor.

Required:

a. Determine the direct materials price variance, direct materials quantity variance, and total direct materials cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.
