My basketball team plays four games per week. During the first four weeks, we lost all 16 of our games. During week 5, we won three games and lost one game, bringing us to 3 wins and 17 losses for the season so far. Each week after that, we win 3 games and lose 1 game. At the end of which week will my team have won at least 65% of its games total for the first time in the season?
