a. A new operating system for an existing machine is expected to cost $690,000 and have a useful life of slx years. The system ylelds an Incremental after-tax Income of $270,000 each year after deducting Its straight-line depreciation. The predicted salvage value of the system Is $29,800. b. A machlne costs $530,000, has a $21,500 salvage value, is expected to last eight years, and will generate an after-tax Income of $68,000 per year after straight-line depreciation. Assume the company requires a 12% rate of return on its investments. compute the net present value of each potential investment. PV of $1. FV of $1.
