Exercise 24-6 Net present value LO P3 for an existing machine is expected to cost $750.000 and have a useful life of six years. The system yields an incremental after-tax income of $160.000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $10,400. b. A machine costs $450,000, 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 $) (Use appropriate factor(s) from the tables provided.)
