During October the plant produced 3,000 ingots and incurred the following costs:
a.
Purchased 16,100 pounds of materials at a cost of $2.75 per pound. There were no raw materials in inventory at the beginning of the month.
b.
Used 10,900 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.)
c. Worked 2,400 direct labor-hours at a cost of $7.50 per hour.
d.
Incurred a total variable manufacturing overhead cost of $6,660 for the month. A total of 1,800 machine-hours was recorded.
It is the company’s policy to close all variances to cost of goods sold on a monthly basis.
