A machine can be purchased for $120,000 and used for five years, yielding the following net incomes. In projecting net incomes straight-line depreciation is applied, using a five-year life and a zero salvage value. Year 1 8,100 Year 2 20,100 Year 3 51,000 Year 4 $30, Year 5 300 $80,400 Net income Compute the machine's payback period (ignore taxes). (Round your intermediate calculations to 3 decimal places and round payback period answer to 3 decimal places.
