Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Kati ya watu 90 kwenye piknik, 1/2 walikunywa soda, hivyo makopo 90 / 2 = <<90/2=45>>45 ya soda yalikunywa.
Kati ya watu 90 kwenye piknik, 1/3 walikunywa maji ya kuchachushwa, hivyo chupa 90 / 3 = <<90/3=30>>30 za maji ya kuchachushwa zilikunywa.
Kati ya chupa 50 za juisi, 4/5 zilikunywa, hivyo 4/5 x 50 = <<4/5*50=40>>40 za juisi zilikunywa.
Jumla, kulikuwa na makopo 45 + 30 + 40 = <<45+30+40=115>>115 na chupa zilizoweza kuchakatwa zilikusanywa.
