a. A new operating system for an existing machine is expected to cost $730,000 and have a useful life of six years. The system yields an incremental after-tax income of $255,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $10,000. b. A machine costs $470,000, has a $35,300 salvage value, is expected to last eight years, and will generate an after-tax income of $74,000 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 FVA of $1) (Use appropriate factor(s) from the tables provided.) X Answer is complete but not entirely correct. Complete this question by entering your answers in the tabs below.
