The NCAA Division I Basketball Tournament begins each year with 64 teams. After each round, a team is eliminated, reducing the number of teams by half. Write an equation to model this scenario.

To write an equation that models this scenario, we can make use of the fact that the number of teams is reduced by half after each round. Let's define "n" as the number of rounds played.

Initially, at the start of the tournament, the number of teams is 64. After the first round, half of the teams are eliminated, leaving us with 64/2 = 32 teams.

Following the same pattern, after the second round, half of the remaining teams are eliminated, leaving us with 32/2 = 16 teams.

We can see that after each round, the number of teams is halved.

Therefore, we can express the number of teams after "n" rounds as:

Number of Teams = 64 / (2^n)

In this equation, "n" represents the number of rounds played, and the equation models the reduction in the number of teams after each round.
