A machine can be purchased for $80,000 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. Net income Year 1 $5,300 Year 2 $13,300 Year 3 $35,000 Year 4 $19,900 Year 5 $53,200 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.)
