Replace Equipment A machine with a book value of $246,500 has an estimated six-year life. A proposal is offered to sell the old machine for $214,200 and replace it with a new machine at a cost of $283,400. The new machine has a six-year life with no residual value. The new machine would reduce annual direct labor costs from $50,000 to $40,000. Note: Consider an outflow a negative value; an inflow a positive value. If an amount is zero, enter "0".
