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

### Instruction:
John has a very inefficient toilet that uses 5 gallons of water per flush and his household flushed 15 times per day.  He replaced it with a toilet that uses 80% less water per flush.  How much water did John save in June?

### Response:
 Choo cha zamani kilikuwa kinatumia galoni 5*15=<<5*15=75>>75 kwa siku.
Hivyo, choo kipya kinaokoa galoni 75*0.8=<<75*0.8=60>>60 kwa siku.
Hivyo, kimeokoa galoni 60*30=<<60*30=1800>>1800 mwezi Juni.
