Compute the time needed for payback for the following example assuming the investment required an up-front capital outlay of $100,000 and the uneven annual cash flows for each year are provided in the table. If an amount is zero, enter "o". For the time needed for payback, enter your answer to one decimal place, if less than one year (i.e. 0.2, 0.5, etc.). Year Unrecovered Investment (Beginning of year) Annual Cash Flow Time Needed for Payback 1 $100,000 $10,000 1 year 2 20,000 3 30,000 4 40,000 5 50,000 Total time needed for payback to the nearest tenth of a year) X years
