The Wyoming Machines Housing Plant manufactures plastic housings for the company's calculators. (Each calculator requires a case.) For each of the next two years, Wyoming expects to sell 640,000 calculators. The beginning inventory of finished shell products at the Casings Plant is 90,000 units. However, the target ending inventory of finished goods for each year is 20,000 units.

Each unit (shell) requires 6 ounces of plastic. At the beginning of the year, 230,000 ounces of plastic are in inventory. Management has set a goal of having plastic on hand equal to three months' sales requirements. Sales and production are carried out evenly throughout the year.
