A company is considering investing $10,000 in a heat exchanger. The heat exchanger will last 5 years, at which time it will be sold for $2,000. The maintenance cost at the end of the first year is estimated to be $1,000 and then will increase by $500 per year over its life. As an alternative, the company may lease the equipment for $3,500 per year, including maintenance. The MARR (before tax) is 5% per year. Perforin a multiparameter sensitivity analysis for this problem, where x=change in initial investment of the heat exchanger and y = change in annual leasing expense. Draw a diagram to illustrate your
