Compute the payback period for each of these two separate investments (round the payback period to two

Question:

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.

Salvage Value
Salvage value is the estimated book value of an asset after depreciation is complete, based on what a company expects to receive in exchange for the asset at the end of its useful life. As such, an asset’s estimated salvage value is an important... Payback Period
