Use Present Worth Analysis to determine whether Alternative A or B should be chosen. Items are identically replaced at the end of their useful lives. Assume an interest rate of 2% per year, compounded annually. Alternative B Alternative A 270 535 70 124 Initial Cost Annual Benefit Salvage Value Useful Life (yrs) 156 124 12 O Alternative A, because its present worth is positive Alternative A, because it costs $15.30 less than Alternative B, in terms of present worth Alternative B, because it costs $15.30 more than Alternative A, in terms of present worth Alternative B, because it only incurs the initial cost once every three years instead of every two years
