If you would like to know how to do this, I suggest reading my answer;
Since Bao saves $179 a month, and Ada saves $145 more, you must add 145 plus 179 together. That would be how much Ada would make in a month. 3 and a half years would be 42 months. 42 times however much 145 plus 179 is would be how you get your answer, (how much Ada saves in 3 and a half year). Hope this helps :) <3
