i = 18% --LHS = 103.63 and i = 20%--LHS = 96.611 Answer: 19.034335% ,do not implement the project if MARR = 20% --- ROR

(I am having trouble when I attempt the linear interpolation. I am getting something greater the 20% which would mean I would implement the project but that is incorrect. Can come please show step by step on how to come up with the right linear interpolation? Please make work readable & type if possible)

5. Consider the following cash flow (CF) information: EOY 0 2 3 4 5 6 7 8 9 10 10 +CF 27 27 27 27 27 27 27 27 27 27 20 = Salvage value -CF 100 0 0 0 20 10 10 10 Draw a cash flow diagram, set up the initial equation, and find the ROR of this invest- ment. If MARR = 20%, then what is your decision
