Rory Company has a machine with a book value of $123,000 and a remaining five-year useful life. A new machine is available at a cost of $118,000, and Rory can also recelve $79,000 for trading in its old machine. The new machine will reduce variable manufacturing costs by $13,000 per year over its five-year useful life. Calculate the incremental income. (Any losses or outflows should be entered with a minus sign.)
