You are tasked with evaluating the purchase of a vending machine for the snack room.

The base price is $4,000 and it would cost another $1,000 to modify the machine to install the machine. The equipment falls in the MACRS 3 year class of depreciation with rates of 33%, 45%, 15% and 7%. The machine would require an investment in snacks (inventory/net operating working capital) of $529. The machine would produce revenue of $3,000 per year with costs of $800 per year. The firms tax rate is 20%.

The firm plans on selling the machine at the end of three years for $1500 and recovering their investment in net working capital at that time as well.

What is the initial investment in the machine?
