Summary: Assumes Jake was not contributing to the 'kitty', so any money provided by him was to be used as surplus to be spread evenly amongst the team. This means 8 players, every game @ $14 per game (i.e. no 'free' games). This equates to a total surplus of $0, giving back to those who have paid extra and requiring those who are short to provide the difference. In this scenario, every player contributing to the 'kitty' pays an equal amount regardless of playing time.
Summary: Also assumes Jake was not contributing to the 'kitty', so any money provided by him was to be used as surplus to be spread evenly amongst the team. This means 8 players, every game @ $20 per game, all games missed @ $14 per game and 2 x games @ $Free. This equates to a total surplus of $400 (if the team wish to have a bash some stage soon), or alternatively can be distributed amongst all players evenly, giving extra to those who paid extra and reducing the amount for those who were short. In this scenario, not every player contributing to the 'kitty' pays an equal amount as the number of games, and the associated cost for these games varies.
