A ball is dropped and bounces up to a height that is $$75 \%$$ of the height from which it was dropped. It then bounces again to a height that is $$75 \%$$ of the previous height and so on. How many bounces does it make before it bounces to a height that is less than $$25 \%$$ of the original height?
