conversations.value: Can you walk me through the solution of: 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?
conversations.from: assistant
conversations.value: 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.
