Hi , thanks for helping me this problem. Can I know the process as detailed as possible? Thanks!!

Example (with a twist) Select one of the two following projects, based on highest equivalent annual annuity (r = 9%). Project A C. C C2 C3 C4 NPV EAA -15 4.9 5.2 5.9 6.2 2.82 .87 -20 8.1 8.7 10.4 2.78 1.10 B Example A machine is expected to produce a net inflow of $4,000 this year and $4,000 next year before breaking. You can replace it now with a machine that costs $15,000 and will produce an inflow of $8,000 per year for three years. Should you replace now or wait a year? ]
