Hi, Nick, I have the same question as you! I can see the graph and did not understand how to right the expression. However, for b I got 20 people.
In each round 15 people get eliminated, the sixth round would have 50 people, and so on. Then for the multiple choice I got the first option because it relates to my answer for b.
Hope this helps!
-awesome :D
