A shellfish processing company is thinking about purchasing a new clam digger for $14,000. The expected net cash flows resulting from the digger are $9,000 in year 1, $7,000 in the 2nd year, $5,000 in the 3rd year, and $3,000 in the 4th year. Should the company purchase this digger if its cost of capital is 12 percent? Please present the NPV as well
