Imagine you have some workers and some handheld computers that you can use to take inventory at a warehouse. There are diminishing returns to taking inventory. If one worker uses one computer, he can inventory 150 items per hour. Two workers sharing a computer can together inventory 200 items per hour. Three workers sharing a computer can together inventory 250 items per hour. And four or more workers sharing a computer can together inventory fewer than 260 items per hour. Computers cost $100 each and you must pay each worker $25 per hour.
Instructions: Round your answer to two decimal places.
1) If you assign one worker per computer, what is the cost of inventorying a single item?
2) If you assign two workers per computer, what is the cost of inventorying a single item?
3) If you assign three workers per computer, what is the cost of inventorying a single item?
4) If you assign four workers per computer, what is the cost of inventorying a single item?
5) How many workers per computer should you assign if you wish to minimize the cost of inventorying a single item?
