Calculate Numbers Required For X Percentage

what I'm trying to do.

Background:
I play a game that requires 5 members to play, however you can have more then 5 members on the team. In order for a player to receive points for playing they must have played at least 30% of the total games played. The problem for me is when trying to figure out how many games someone needs to play to get to 30%, the total goes up as they play those games.

What I would like to accomplish:
I'm looking for help on a formula that would figure out how many games a player would need to play to get to 30%. I have a column that is total games played, %of games played by player, games played by player, and games needed to play to get to 30%. Basically the user would enter the # of games played by each player, and the total games played overall for the team for that week, the spreadsheet would then show the # of games each player that isn't above 30% would need to play.

I tried to make the question as clear as possible, if anyone needs clarification,
