Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1740,000; the new one will cost, $2,105,000. The new machine will be depreciated stralght-line to zero over its five-year Iife. It will probably be worth about $495,000 after five years The old computer Is belng depreciated at a rate of $384,000 per year. It will be completely wrtten off in three years. If we don't replace It now, we will have to replace it In two years. We can sell it now for $585,000; In two years, It will probably be worth $171,000. The new machine wll save us $365,000 per year In operating costs. The tax rate Is 24 percent, and the discount rate is 9 percent a-1 Calculate the EAC for the the old computer and the new computer.
