A piece of research equipment is expected to require an investment of $18,000, with $6,000 committed now and next year $7000 while the remaining $6K will be pay out at the end of year 2. Annual operating costs for the system are expected to start in the first year and continue at $800 per year. The life of the equipment is 8 years with a salvage value of $500. Calculate the CR and AW values for the system, if the corporate MARR is 14.32% per year.
Year wise cash flow are given
Present value "= \\frac{cf }{ ( 1+i)^n}"
For year 0 "= \\frac{-6000}{ (1+14.32 \\%)^0} = -6000"
For year 1 "= \\frac{-6000}{ (1+14.32 \\%)^1}= -5248. 42"
For year 2 "= \\frac{-6000}{(1+14.32 \\%)^2}= -4590. 99"
For year 8 "= \\frac{-500}{ (1+14.32 \\%)^8}= 171.39"
Capital recovery "= -6000-5248.42-4590.99+171.39"
Capital recovery "= - 15668.02"
Annual worth "= -15668.02- 800 = -16468.02"
