a. A new operating system for an existing machine is expected to cost $560,000 and have a useful life of six years. The system yields an incremental after-tax income of $250,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $16,800. b. A machine costs $460,000, has a $21,500 salvage value, is expected to last eight years, and will generate an after-tax income of $80,000 per year after straight-line depreciation Assume the company requires a 12% rate of return on its investments.
