conversations.value: I would love to understand how to solve this problem: A waterpark opens up and charges $30 for admission.  Kids' tickets are half price.  If a group of people brings a soda, they can get 20% off the total price of admission.  Janet gets tickets for 10 people and 4 of them are children.  She buys a soda for $5 to take advantage of the discount for her group.  How much did she pay for everything?
  Can you explain?
conversations.from: assistant
conversations.value: She bought 10-4=6 adult tickets
  So 6*30=$180 was the cost for adult tickets
  Children tickets cost 30/2=$15 each
  So the children tickets cost 15*4=$60
  So the total cost of tickets is 60+180=$240
  They get a 240*.2=$48 discount
  So the tickets cost 240-48=$192
  So in total she paid 192+5=$197
