The Casings Plant of Wyoming Machines makes plastics shells for the company's calculators. (Each
calculator requires one shell.) For each of the next two years, Wyoming expects to sell 160,000
calculators. The beginning finished goods inventory of shells at the Casings Plant is 20,000 units.
However, the target ending finished goods inventory for each year is 5,000 units.

Each unit (shell) requires 6 ounces of plastic. At the beginning of the year, 60,000 ounces of plastic
are in inventory. Management has set a target to have plastic on hand equal to two months' sales
requirements. Sales and production take place evenly throughout the year.
