Hope that helps someone, I forgot to get the exact % of all these, but you get the point! Should help newbs I guess. Hope you enjoy!
One more thing, I dont remember if it tells you in the intro that you can click and delete trees for 75$, I did not realize this till my second attempt. It helps a great deal. Either I missed it in the intro or its not there, either way, might help someone new.
