Check my wor a. A new operating system for an existing machine is expected to cost $610,000 and have a useful life of six years. The system yields an incremental after-tax income of $275,000 each year after deducting its straight-line depreciation The predicted salvage value of the system is $13,000 b. A machine costs $420,000, has a $23,600 salvage value, is expected to tast eight years, and wil generate an after-tax income of $72,000 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. PVA of S1, and EVA of $1) (Use appropriate factor(s) from the tables provided.)
