The Diving Club offers 2 beginning diving classes on weekdays and 4 beginning classes on each day of the weekend. Each class has room for 5 people. How many people can take classes in 3 weeks? Let's answer step by step:
There are 2 classes x 5 days = 10 classes on weekdays. There are 4 classes x 2 days = 8 classes on weekends. There are a total of 10 + 8 = 18 classes per week. So each week, 18 x 5 = 90 people can take classes. Thus, 90 x 3 = 270 people can take classes in 3 weeks. The answer: 270.
