Washington Federal Hospital plans to invest in a new X-ray machine. The cost of the machine is $800,000. The machine has an economic life of seven years, and it will be depreciated over a seven-year life to a $100,000 salvage value.

Additional revenues attributed to the new machine will amount to $600,000 per year for seven years. Additional operating costs, excluding depreciation expense, will amount to $400,000 per year for seven years. Over the life of the machine, net working capital will increase by $50,000 per year for seven years.
