A high school sponsored a badminton tournament. After each round,

one-half of the players were eliminated. If there were 64 players at the

start of the tournament, which equation models the number of players

left after 3 rounds?

(1) y = 64 (1 -,5) 3

(3) y = 64 (1 - 3) 0.5

(2) y = 64 (1 + 5) 3

(4) y = 64 (1 + 3) 0,5
