In 2021 I bought 1/3 of ACO's Sushi House at BAM for 550,000TL. After 3 years I sold half of my shares to Yasin for 1,500,000TL. The next year, because of a new virus, the business did poorly and I decided to leave the sushi business but I had to pay Ahmet Can 100,000TL to share our losses. What is the rate of return of my investment?

Write your answer as a decimal number, with at least one digit after the decimal point. If your result is 10.5% just write 10.5 (DO NOT write it as 0.105 or DO NOT put a percentage sign)
