Your firm specializes in recycling used plastics into consumer goods. You have three production opportunities:

1. You can produce plastic utensils for a revenue of $30,000 while production will cost $15,000.

2. Alternatively, you can produce lampshades: you calculate that at the optimal production, you expect to sell 2,000 lampshades every year at $10 each, and your average total cost per lampshade will be $2.

3. You also have the option to shut down your factory and produce nothing at a cost of $1,000 a year.
