The Casings Plant of Wyoming Machines makes plastics shells for the companys calculators. (Each calculator requires one shell.) For each of the next two years, Wyoming expects to sell 670,000 calculators. The beginning finished goods inventory of shells at the Casings Plant is 70,000 units. However, the target ending finished goods inventory for each year is 15,000 units.

Each unit (shell) requires 6 ounces of plastic. At the beginning of the year, 220,000 ounces of plastic are in inventory. Management has set a target to have plastic on hand equal to four months sales requirements. Sales and production take place evenly throughout the year.
