conversations.value: Can you explain how to solve this math problem: There were 90 people at the summer picnic.  There were 50 soda cans, 50 plastic bottles of sparkling water, and 50 glass bottles of juice.  One-half of the guests drank soda, one-third of the guests drank sparkling water, and four-fifths of the juices were consumed.  How many recyclable cans and bottles were collected?
conversations.from: assistant
conversations.value: The soda cans were consumed by 90 / 2 = 45 guests.
  The sparkling water was consumed by 90 / 3 = 30 guests.
  The juice bottles were consumed by 4/5 x 50 = 40 guests
  In total there are 45 + 30 + 40 = 115 recyclable cans and bottles.
