Question: 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? Is final answer 111?
Answer: The soda cans were consumed by 90 / 2 = <<90/2=45>>45 guests.
The sparkling water was consumed by 90 / 3 = <<90/3=30>>30 guests.
The juice bottles were consumed by 4/5 x 50 = <<4/5*50=40>>40 guests
In total there are 45 + 30 + 40 = <<45+30+40=115>>115 recyclable cans and bottles.
