Applied Nanotech is thinking about introducing a new surface cleaning machine. The marketing department has come up with the estimate that Applied Nanotech can sell 15 units per year at $297,000 net cash flow per unit for the next four years. The engineering department has come up with the estimate that developing the machine will take a $13.9 million initial investment. The finance department has estimated that a discount rate of 11 percent should be used.
