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

### Instruction:
Tony drinks 72 ounces of water per day. He decides that to stop wasting plastic, he will buy a reusable metal bottle. If he buys an 84-ounce water bottle, how many times will he fill it each week?

### Response:
 Tony ananywa onsi 504 za maji kwa wiki kwa sababu 72 x 7 = <<72*7=504>>504
Atahitaji kujaza mara 6 kwa sababu 504 / 84 = <<504/84=6>>6
