For a new equipment, the initial investment is $20,000. The expected revenue per year is $10,000. The estimated life of the equipment is 10 years. Cost of annual operating and maintenance is estimated to be $3,000 and at the end of 10 years, the machine may be sold at $1,500. MARR for this equipment is set 10% per --year.-Investigate PW over a range of 20%in the estimates for: i Capital investment ii. Annual net cash flow, and iii. Useful life Plot a diagram that summarizes the sensitivity of PW to the given percent deviation changes in each factor estimate.
