25. Harold Grey owns a small farm in the Salinas Valley that grows apricots. The apri- cots are dried on the premises and sold to a number of large supermarket chains Based on past experience and committed contracts, he estimates that sales over the next five years in thousands of packages will be as follows: UAWN Year 1 2 3 4 5 Forecasted Demand (thousands of packages) 300 120 200 110 135 Assume that each worker stays on the job for at least one year, and that Grey currently has three workers on the payroll. He estimates that he will have 20,000 packages on hand at the end of the current year. Assume that, on the average, each worker is paid $25,000 per year and is responsible for producing 30,000 pack- ages. Inventory costs have been estimated to be 4 cents per package per year, and shortages are not allowed. Based on the effort of interviewing and training new workers, Farmer Grey estimates that it costs $500 for each worker hired. Severance pay amounts to $1,000 per worker
