A machine can be purchased for $60,000 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 Year 2 $3,900 $9,900 Year 3 Year 4 $32,000 $14,700 Year 5 $39,600 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.)
