The Boxing Tournament! Problem 2

Student have enjoyed working on The Boxing Tournament, problem number 2 as we prepare for I Love Math Day.  In hopes that this challenge can get discussed at home, here is the problem.  If you have any questions, any student in grades 6 through 8 can help.


The Boxing Tournament
An elimination boxing tournament was organized.  There were 114 participants, so the first round had 57 matches.  (In this tournament, no match results in a tie.  Each match determines a winner and a loser.)

The 57 winners were paired up for the second round, resulting in 28 matches, with one boxer left over.  That lucky boxer was allowed to proceed to the next round automatically.

This procedure was followed until one boxer won the tournament. 

How many total matches were required in order to determine the winner?


Suppose there were 199 boxers participating in the tournament.  How many total matches would be required?



Can you generalize?  If there are  n  boxers total, how many matches will be required to determine the winner?
