Solution
Within the conference, there are 8 teams, so there are 
pairings of teams, and each pair must play two games, for a total of 
games within the conference.
Each team also plays 4 games outside the conference, and there are 8 teams, so there are a total of 
games outside the conference.
Therefore, the total number of games is 
, so 
is our answer.
