An investment has the cash flow profile shown below: Year 0 1 2 3 Cash Flow -$100,000 $40,000 $ 50,000 $60,000 Year Cash Flow 4 $40,000 There are at most 5 6 7 -$ 100,000 $60,000 -$ 10,000 Year 8 9 10 Cash Flow $40,000 $ 30,000 $10,000 Using an internal rate of return analysis, from Descartes' rule of signs, what is the maximum number of positive internal rates of return? positive-valued internal rate of return solutions. Using an internal rate of return analysis, is Norstrom's criterion satisfied? Why or why not? time(s). , Norstrom's criterion satisfied, because cumulative cash flow changes signs Using an internal rate of return analysis, identify the real, positive-valued root for the polynomial equation used to calculate the internal rate of return. %
