Based on cost considerations as well as storage space, the company has decided to order $10$ of these each time and order is placed. The holding cost is $$1$ per week for each unit that is left in inventory at the end of the week. The stockout cost has been set as $$40$ per stockout. The company has decided to place and order whenever there are only two refrigerators left at the end of the week. Simulate $10$ weeks of operation for Dumoor Appliance assuming there are currently $5$ units in inventory. Determine what the weekly stockout cost and weekly holding cost would be for the problem.
