A five-year project has a projected net cash flow of $15,000,$25,000,$30,000,$20,000, and $15,000 in the next five years. It will cost $50,000 to implement the project. If the required rate of return is 20 percent, conduct a discounted cash flow calculation to determine the NPV. The estimated NPV is: A: 11200 B 18000 C 14500 D 13000
