A machine with a book value of $25,000 has an estimated remaining life of 5 years. A proposal is offered to sell the old machine for $18,800 and replace it with a new machine at a cost of $40,000. The new machine has a 5-year life with no residual value. The new machine would reduce annual direct labor costs from $17,500 to $9,000. Prepare a differential analysis dated June 2 on whether to continue with the old machine (Alternative 1) or replace the old machine (Alternative 2).
