I have tried several times at trying to get the sustainable growth rate but none of the answers are right. 12.12% is not the answer.

You've collected the following information about Sully, Inc.: Profit margin 4.32% Total asset turnover 2.30 Total debt ratio Payout ratio 17% What is the sustainable growth rate for the company? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) Sustainable growth rate 12.12
