Exercise 33

Refer to the information in Exercise 25-5. Assume the company requires a 10% rate of return on its investments. Compute the net present value of each potential investment. (Round to the nearest dollar.)
Reference: Exercise 25-5.
Compute the payback period for each of these two separate investments (round the payback period to two decimals):
a. A new operating system for an existing machine is expected to cost $520,000 and have a useful life of six years. The system yields an incremental after-tax income of $150,000 each year after deducting its straight-line depreciation. The predicted salvage value of the system is $10,000.
b. A machine costs $380,000, has a $20,000 salvage value, is expected to last eight years, and will generate an after-tax income of $60,000 per year after straight-line depreciation.
