e. A new operating system for an existing machine is expected to cost $760,000 and have a useful life of six years. The system yields an incremental after-ta): income of $150,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $22,200. In. A machine costs $5Tr'0,00l0r has a $23,600 salvage value, is expected to last eight years, and will generate an aftertax income of $38,000 per year after straight-line depreciation. Assume the company requires a 10% rate of return on its investments. Compute the net present value of each potential investment.
