Consider a project that requires an initial investment of $502, pays $106 one year from today (at t = 1), pays $202 two years from today (at t = 2), and pays $353 three years from today (at t = 3). Rounded an accurate to three decimal places, what is the payback period for this project? (Example: if we had a much longer-term project of nine years, and you found the payback period was 7.2345 years...your answer would be entered as 7.235.).
