Hello, this is a practice problem for a class I'm struggling with. The professor isn't much help, I'd really appreciate if someone here can answer this and break it down so I can follow the logic and see where I'm going wrong with these problems.

During the last four years, a certain mutual fund had the following rates of return: Rate of Return At the beginning of 2014, Alice invested $2,237 in this fund. At the beginning of 2015, Bob decided to invest some money in this fund as well. How much did Bob invest in 2015 if, at the end of 2017, Alice has 29% more than Bob in the fund? Round your answer to the nearest dollar
