1. 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 6,400 units of product were as follows:

   	Standard Costs		Actual Costs
   Direct materials	8,300 lb. at $5.00		8,200 lb. at $4.90
   Direct labor	1,600 hrs. at $18.30		1,640 hrs. at $18.50
   Factory overhead	Rates per direct labor hr.,
   	based on 100% of normal
   	capacity of 1,670 direct
   	labor hrs.:
   		Variable cost, $4.70	$7,440 variable cost
   		Fixed cost, $7.40	$12,358 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.
