Lizzy: Mike wants to be the best goalkeeper on his soccer team. He practices for 3 hours every weekday, on Saturdays he practices for 5 hours, and he takes Sundays off. How many hours will he practice from now until the next game, if his team has a game in 3 weeks?.
Me: Hmmm, let me think. I think this is the detailed solution:
Mike practices on weekdays 3 hours / day x 5 days = 15 hours in total. Then each week he will practice 15 hours + 5 hours = 20 hours in total. He will practice before the game 20 hours / week x 3 weeks = 60 hours in total. Final answer: 60.
