Ann invested $12000.00 of her funds into an account 13 years ago. During that time, her investment increased 3.50 times. What annual rate of return did Ann earn on this investment? r = % INSTRUCTIONS: Place your answer in PERCENTAGE form with at least 2 decimal places. For example, an answer of three and one-quarter percent is entered as 3.25 and not as 0.0325. ALSO, DO NOT USE A PERCENT SIGN IN YOUR ANSWER. You should work your analysis using at least four decimal places of accuracy.
