Haley's softball team has a phone tree in case a game is cancelled. The coach calls three players. THen each of those players call three players, and so on how many players will be notified during the third round of calls

27

Step-by-step explanation:

If we follow the amount of players called,

Coach called three/3

Players called three/3

Three players called three/3

And make it into a equation, 1 x 3 = 3

Those three people call three more: 3 x 3 = 9

Those nine people call three more: 9 x 3 = 27
