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 Year 3 Year 2 Year 4 Year 5 Net income $8,100 $20,100 $51,000 $30,300 $80,400 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.)
