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?
How many games has Bill won? ** First find the total number of games Bill has won: 200 games * 63% = <<200*63*.01=126>>126 games
How many games does Bill play? ** Then find how many of the next 100 games he wins by subtracting the number he loses from the total: 100 games - 43 games = <<100-43=57>>57 games
How many games does Bill win? ** Then add his new wins to his old wins to find his total wins: 57 games + 126 games = <<57+126=183>>183 games
How many games has Bill played? ** 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 = <<200+100=300>>300 games
What is Bill's new win percentage? ** 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%
