After 10 years the machine can be sold for $5,000. Machine B could be purchased for $40,000. It also will last 10 years and will require maintenance costs of $4,000 in year three, $5,000 in year six, and $6,000 in year eight. After 10 years, the machine will have no salvage value. What is the present value of each alternative? What machine should they purchase
