Read the requirements. Requirement 1. Compute the payback, the ARR, the NPV, the IRR, and the profitability index of this investment. First, determine the formula and calculate payback. (Round your answer to one decimal place, X.X.) Amount invested 1950000 Expected annual net cash inflow 480000 = = Payback 4.1 years Next, determine the formula and calculate the accounting rate of return (ARR). (Round the percentage to the nearest tenth percent, X.X%.) Average annual operating income Average amount invested = = ARR % Calculate the net present value (NPV). (Enter any factor amounts to three decimal places, X.XXX.) Net Cash Annuity PV Factor Present Years 1-8 Present value of annuity 0 Investment Inflow (i=12%, n=8) Value 480000 Net present value of the investment The IRR (internal rate of return) is between 18-20% Finally, determine the formula and calculate the profitability index. (Round your answer to two decimal places, X.XX.) Choose from any list or enter any number in the input fields and then continue to the next question.
