The athletics director at Peter's school has created a phone tree that is used to notify team players in the event a

game has to be canceled or rescheduled. The phone tree is initiated when the director calls two captains. During

the second stage of the phone tree, the captains each call two players. During the third stage of the phone tres

these players each call two other players. The phone tree continues until all players have been notified. If thereas

50 players on the teams, how many stages will it take to notify all of the players?
