A machine can be purchased for $285,000 and used for five years, yielding the following net incomes. In projecting net incomes, double-declining depreciation is applied using a five-year life and a zero salvage value. Year 1 Net income $12,000 Year 2 $37,000 Year 3 $59,000 Year 4 $59,000 Year 5 $139,000 Compute the machine's payback period (ignore taxes). (Round payback period answer to 3 decimal places.)
