a. A new operating system for an existing machine is expected to cost $630,000 and have a useful life of six years. The system yields an incremental after-tax income of $160,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $25,400. b. A machine costs $580,000, has a $39,500 salvage value is expected to last eight years, and will generate an after-tax income of $76,000 per year after straight-line depreciation Assume the company requires a 10% rate of return on its investments.
