a. A new operating system for an existing machine is expected to cost $600,000 and have a useful life of six years. The system yields an incremental after-tax income of $180,000 each year after deducting its straight line depreciation. The predicted salvage value of the system is $25,400. b. A machine costs $440,000, has a $34 700 salvage value, is expected to last eight years, and will generate an after-tax income of $72,000 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 PV of $1. FV of $1. PVA of $1. and EVA S1) (Use appropriate foctor(s) from the tables provided.)
