[Question]: James watched 2 episodes of Jeopardy and 2 episodes of Wheel of Fortune. Jeopardy is 20 minutes and Wheel of Fortune is twice as long. How many hours did he watch TV?
[Answer]: He watched 2 * 20 = 40 minutes of Jeopardy. Wheel of Fortune is 2 * 20 = 40 minutes each. So he watched it for 40 * 2 = 80 minutes. So he watched 40 + 80 = 120 minutes of TV. That means he watched 120 / 60 = 2 hours of TV.
So the answer is 2.

[Question]: 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?
[Answer]:
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%.
So the answer is 61.
