Question

64 teams participate in a softball tournament in which half the teams are eliminated after each round of play.

b. How many teams remain in play after 3 rounds?

Answer 1

The first round has 64 teams, so 64/2 = 32 after the first round.

The second round has 32 teams left, so 32/2 = 16 after the second round.

The third round has 16 teams left, so 16/2 = 8 teams left after the 3rd round.
