My question is: Bill has played 200 games of poker and won 63% of them. If he plays 100 more games and loses 43 of them, what is his new win percentage? Your thoughts:
First find the total number of games Bill has won: 200 games * 63% = 126 games. Then find how many of the next 100 games he wins by subtracting the number he loses from the total: 100 games - 43 games = 57 games. Then add his new wins to his old wins to find his total wins: 57 games + 126 games = 183 games. Then add the old total number of games to the new total number of games to find the overall total number of games: 200 games + 100 games = 300 games. Then divide the total number of games Bill won by the overall total number of games and multiply by 100% to find the percentage of games he won: 183 games / 300 games * 100% = 61%. The final answer: 61.
