Conduct a sensitivity analysis of PW to MARR for both ovens based on the previous problem data and discuss the feasibility region of both ovens in terms of MARR values between 1% and 20%, with 1% incremental increase. Show your PW analysis results in a tabulated format as well as graphical format. Example table can be prepared as follows. 127B 334A MARR 1% 2% 3% 4% 5% 6% 7% 8% 9% 10% 11% 12% 13% 14% 15% 16% 17% 18% 19% 20% Model 127B Model 334A $50,000 $80,000 10 5 Initial Investment Estimated Life End of Life Salvage Annual Income $10,000 so $19,400 $26,000 Annual Expense $10,000 $6,000
