She almost had a very interesting question that I'm going to finish for her (because it's very easy math, I'm just a little durrhurr):

If a dollar is 100 cents
And tax is 10%
How many people can you pass that dollar to before it reaches ~50¢, ~25¢, ~10¢, ~1¢.

How many times can you pass money from one hand to another, before a 10% tax has taken 50% or more of the total value? Genuinely would love to see the math on this (if anyone could tell me the formula as well that would be based)
