Can I get a step by step explanation on Excel? Greatly appreciated!

You are selecting equipment for a project. There are two machines under consideration. They will provide the same function, but there are difference in cost, benefits, life and other details. Costs, machine prices AND salvage all go up at the rate of inflation. Costs and benefits are shown for year 1 . Benefits go up by the % given. Salvage costs are given for an 12 yr old machne A or a 6 yr old machine B TODAY. Adjust with inflation. Help your employer to determine which machine is the best choice. Create the net cash flow chart for both machines. Deterine the NPW for both machines. Determine the EUAW for both machines. Determine the NFW for both machines. Determine the IRR for both machines Detemine the DELTA IRR . Which machine will you select? Why? Graph the NPW versus MARR chart for both machines (both curves on the same graph)
