Hamline Manufacturing makes a single product. Standard costs are given below.
Manufacturing Cost Elements Quality * Price = Cost
Direct Materials 6 oz. * $0.90 = $5.40
Direct Labor 0.5hrs * 12.00 = 6.00
Manufacturing overhead 0.5hrs * 4.80 = 2.40
$13.80
During the month, the following transactions occurred in manufacturing 10,000 units.
58,000 ounces of materials were purchased at $1.00 per
ounce.
All the materials purchased were used to produce the 10,000
units.
4,900 direct labor hours were worked at a total labor cost of
$56,350.
Variable manufacturing overhead incurred was $15,000 and fixed
overhead incurred was $10,400.
Compute the total variance and the variances for direct materials and direct labor elements.
