Hi for requirement B, I cannot figure out the Net Present Value. it keeps saying that 533,631is incorrect, while everything else is correct.

Exercise 24-6 Net present value LO P3 a. A new operating system for an existing machine is expected to cost $769,000 and have a useful life of six years. The system yields an incremental after-tax income of $225,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $85,000. b. A machine costs $530,000, has a $50,000 salvage value, is expected to last eight years, and will generate an after-tax income of $135,000 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.) Complete this question by entering your answers in the tabs below.
