"A special-purpose turnkey stamping machine was purchased four years ago for $20,000. It was estimated at that time that this machine would have a life of 10 years, a salvage value of $5,000, and a removal cost of $2600. These estimates are still good. The machine has annual operating costs of $2,800. A new machine that is more efficient will reduce the operating costs to $1100, but it will require an investment of $14,000 plus $2,000 for installation. The life of the new machine is estimated to be 12 years, a salvage of $1,900, and a removal cost of $800. An offer of $10,500 has been made for the old machine, and the purchaser is willing to pay for removal of the machine. Find the ANNUAL EQUIVALENT COST of the preferred alternative (replacing or continuing with the present machine). The firm`s interest rate is 15% for any project justification. Ignore the effect of taxes and depreciation."
