Your company is deciding whether to invest in a new machine. The new machine will increase cash flow by $323,000 per year. You believe the technology used in the machine has a 10-year life; in other words, no matter when you purchase the machine, it will be obsolete 10 years from today. The machine is currently priced at $1,730,000. The cost of the machine will decline by $105,000 per year until it reaches $1,205,000, where it will remain. If your required return is 13 percent, calculate the NPV today. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) If your required return is 13 percent, calculate the NPV if you wait to purchase the machine until the indicated year. ( A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) Answer is complete but not entirely correct
