You supervise an aging production line that constantly needs maintenance and new parts. Last month you spent $25,000 replacing a failed controller. Should the following plan be accepted if the interest rate is 15%? The net installed cost of the new line to replace the old line is $600,000 with a useful life of six years. In the first year its operating cost will be $100,000, and it will generate annual revenues of $300,000.
Present worth = -600000 + (300000 - 100000)*(P/A,15%,6)
= -600000 + (300000 - 100000)*3.784483
= 156896.60
As NPW > 0, new line should be installed
