Hadley's softball team has a phone tree in case a game is cancelled.The coach calls 3 players. Then each of those players calls 3 players and so on.How many players will be notified during the 3rd round of calls?
I think it's 27
1st round: 3
2nd round: 9
3rd round: 27
You're right.
27
1st round is 3 because 3x1=3
2nd round is 9 because 3x3=9
3rd round is 27 because 9x3=27
To determine the number of players who will be notified during the 3rd round of calls, we can use the concept of geometric progression.
In the first round, the coach calls 3 players. In the second round, each of those 3 players calls 3 more players. So, in the second round, a total of 3 x 3 = 9 players are notified.
Now, in the third round, each of the 9 players from the second round calls 3 more players. Therefore, the total number of players notified in the third round will be 9 x 3 = 27 players.
So, during the 3rd round, 27 players will be notified.
