the washington school pta set up a phone tree in order to reach all of its members. Each person's respnsibility, after recievin ga call, is to call two other assigned members until all members have been called. If we assume that everyone is at home and answers the phone, and that each phone call takes 30 seconds, what is the least amount of time necessary to reach all 85 members?
-if you can find the answer please explain the steps you took to do so.
Thank you!
