1. 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 78,000 units of product were as follows:

   	Standard Costs		Actual Costs
   Direct materials	202,800 lbs. at $5.50		200,800 lbs. at $5.30
   Direct labor	19,500 hrs. at $16.10		19,950 hrs. at $16.40
   Factory overhead	Rates per direct labor hr.,
   	based on 100% of normal
   	capacity of 20,350 direct
   	labor hrs.:
   		Variable cost, $2.90	$55,980 variable cost
   		Fixed cost, $4.60	$93,610 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.
