Compute the payback period for each of these two separate Investments, o. A new operating system for an existing machine is expected to cost $250,000 and have a useful life of five years. The system yields an incremental after-tax income of $72,115 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $10,000, b. A machine costs $200,000. has a $13.000 salvage value is expected to last eleven years, and will generate an after-tax income of $39.000 per year after straight line depreciation, Answer is complete but not entirely correct.
