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?

A machine has a 10-year life. It costs $5,000 to install today, and annual maintenance costs in years 1-10 are $500 per year. If the discount rate is 7%, what is the machine's equivalent annual annuity (EAA)? A project requires an initial investment of $20,000 today (i.e. year 0). Expected future cash flows in years 1-4 are $8000; $2000; $3000 and $6000 respectively. If the discount rate is 8%, what is the NPV? What is the IRR?

4) Machine A costs $35,000, lasts 3 years and has a salvage value of $7,500. Machine B costs $25,000, lasts 2 years and has a salvage value of $3,500. The machines can be purchased at the same price with the same salvage value in the future, and are needed for a 6 year project. Which machine would you purchase and why? Provide justification using an Annualized Equivalent Cost analysis. Interest is 10% annual rate, compounded annually. Answer______________________________________
