A new operating system for an existing machine is expected to cost $735,000 and have a useful life of six years. The system yields an incremental after-tax income of $215,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $75,000.

A machine costs $510,000, has a $46,000 salvage value, is expected to last eight years, and will generate an after-tax income of $125,000 per year after straight-line depreciation.
