DM and DL standards and variances: material and direct labor standards for a product are: Direct materials: 2 feet per unit @ $5 per foot; Direct labor: .4 DLH @ $12 per hour. During the period, produced 1,000 units with the following costs: 2,100 feet of material at a cost of $10,080, 380 DLH at a cost of $4,522. Calculate 1) standard direct materials cost per unit 2) standard direct labor cost per unit 3) direct materials cost variance 4) direct materials efficiency variance 5) direct labor cost variance 6) direct labor efficiency variance. For items 3-6, explain what the variance indicates (for example, a favorable material cost variance indicates that the actual cost per foot of materials was less than the standard cost per foot ($5))
