Give the step-by-step reasoning process and then the final answer. 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?
User
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.
The final answer: 115.
