the rate of interest is 7% per year. Altirnative 1: Initial purchase price = $3050000, Annual operating cost $40000 at the end of 1st year and increasing by $2000 in the subsequent years till the end of useful life, Annual income - $560000, Salvage value = $1050000, Useful life = 4years. Altirnative 2: Initial purchase price = $4000000, Annual operating cost = $55000, Annual income $600000 at the end of 1st year and increasing by $5000 in the subsequent years till the end of useful life, Salvage value = $1000000, Useful life = 6 years. Altirnative 3: Initial purchase price = $2500000, Annual operating cost $45000 at the end of 1st year and increasing by $3000 in the subsequent years till the end of useful life, Annual income = $120000, Salvage value = $550000, Useful life = 12 years.
