compute the life cycle cost of a reciprocating compressor with first cost of 140000 annual maintenance costs of 15000 , salvage value of 30000 and life of eight years . the rate of return is 8%

5. (20 pts) An existing electrical power line needs to have its capacity increased, and this can be done in either of two ways. The First Method is to add a second conductor to each phase wire, using the same poles, insulators, and fittings, at a construction cost of $20,000. The Second Method for increasing capacity is to build a second line parallel to the existing line, using poles, insulators, and fittings, at a construction cost of $28,000. At some time in the future, the line will require another increase in capacity, with the First Method now requiring a at a cost of $38,500, and the Second Method requiring added conductors at a cost the interest rate is 4%, how many years between the initial expenditure and the future expenditure will make the First Method and the Second Method economically second line of $2700. 5.
