Suppose you own your own business and you are considering an investment. If you undertake the investment, it will pay $3,000 at the end of each of the next 4 years. The opportunity requires an initial investment of $9,000 plus an additional investment of $9,000 at the end of the third year. What is the NPV of this opportunity if the interest rate is 3.2% per year? Round your answer to one decimal place. You have to round up if economic reasoning requires you to do so. Do NOT write the dollar sign ($). Do not forget the minus sign if needed
