A machine can be purchased for $210,000 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 $14,200 Year 2 $35,200 Year 3 $91,000 Year 4 $53, 100 Year 5 $140,800 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.)
