Zhang Lei spent $20.00 during his last outing at the bowling alley. This included a one time shoe rental fee of $3.50. He spent the rest of the money on bowling a number of games. If it took Zhang Lei 45 minutes to bowl each game and he spent 2 hours and 15 minutes bowling, how much did it cost per game.
Q. Zhang Lei spent $20.00 during his last outing at the bowling alley. This included a one time shoe rental fee of $3.50. He spent the rest of the money on bowling a number of games. If it took Zhang Lei 45 minutes to bowl each game and he spent 2 hours and 15 minutes bowling, how much did it cost per game.
Subtract shoe rental fee: First, subtract the shoe rental fee from the total amount spent to find out how much money was spent on the games alone.$20.00−$3.50=$16.50 spent on games.
Convert bowling time: Next, convert the total bowling time from hours and minutes to minutes. 2 hours and 15 minutes is the same as 2×60 minutes + 15 minutes, which equals 135 minutes.
Divide total time: Now, divide the total time spent bowling by the time it takes to bowl one game to find out how many games he played. 135 minutes ÷45 minutes per game = 3 games.
Find cost per game: Finally, divide the total amount spent on games by the number of games to find the cost per game.$16.50÷3 games=$5.50 per game.
