Using Microsoft Excel, create an investment cash-flow diagram that will have a present worth of zero using MARR = 12%. The study period needs to be exactly 9 years and each year should have at least one unique cash-flow that is different from the cash-flows over the other years. Your answer should contain a table showing the cash-flows for each year and a graphical representation of the cash-flows (cash-flow diagram). PLEASE SHOW ME HOW TO SOLVE THIS QUESTION USING MICROSOFT EXCEL ( spreadsheet ) . Many Thanks
