A machine costs $35,000 to buy and $5,000 per year to operate and maintain. It will have a salvage value of $8,000 in 9 years. It will generate $10,000 per year in net revenue for the first four years, and then the revenue will fall by $1,000 each year after. If the company purchasing the machine uses a MARR of 7% to make project , find the NPW, NFW, and AW. Is this project worth undertaking if no loss is expected?
