Because of rapidly advancing technology, Southern Publications Corporation is considering replacing its existing typesetting machine with leased equipment. The old machine, purchased two years ago, has an expected useful life of six years and is in good condition. Apparently, it will continue to perform as expected for the remaining four years of its expected useful life. A four-year lease for equipment with comparable productivity can be obtained for $8,000 per year. The following data apply to the old machine:
