A machine with a book value of $80,000 has an estimated five-year life. A proposal is offered to sell the old machine for $50,500 and replace it with a new machine at a cost of $75,000. The new machine has a five-year life with no residual value. The new machine would reduce annual direct labor costs from $11,200 to $7,400. Prepare a differential analysis dated April 11 on whether to continue with the old machine (Alternative 1) or replace the old machine (Alternative 2).
