Your client requests you to evaluate two manufacturing machines for a facility. Assume an interest rate of 6%. Machine 1: Initial cost = $250,000 Life Span = 12 years Salvage value = $30,000. After 6 years, $60,000 in maintenance is required in addition to annual O&M costs of $9,000 each year (starting at the beginning of the project). The machine produces widgets with a value of $105,000 per year. Machine 2: Initial cost = $175,000 Life Span = 8 years Salvage value = $20,000. After 4 years, $15,000 in maintenance is required in addition to annual O&M costs of $10,000 each year (starting at the beginning of the project). The machine produces widgets with a value of $90,000 per year. Determine the most cost effective solution for your client by evaluating the net present worth
