A commercial oven with a book value of $50,910 has an estimated remaining 5 year life. A proposal is offered to sell the oven for $15,910 and replace it with a new oven costing $90,910. The new machine has a 5-year life with no residual value. The new machine would reduce annual maintenance costs by $17,480.

Provide a differential analysis on the proposal to replace the commercial oven.
