Reference no: EM13300107

A proposed investment consists of constructing a building, purchasing production machinery, and operating for 20 years; its first cost is $250,000 with a salvage value $50,000. Since the maximum life of the machinery is 12 years, it will be necessary to renew the machinery once during the 20 years. The first cost of the machinery is $132,000 and its salvage value is $132,000/(age, years). The annual income is less the operating expense is expected to be $50,000. Annual interest is 6 percent compounded annually.
