HOW DO I CALCULATE?

A machine can be purchased for $70,000 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 $4,600 Year 2 $11,600 Year 3 $ 34,000 Year 4 $17,300 Year 5 $46,400 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.)
