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

### Instruction:
 Kila darasa linatumia karatasi 200 kwa siku. Shule inatumia jumla ya karatasi 9000 kila wiki. Ikiwa kuna siku 5 za shule, darasa ngapi zipo shuleni?


### Response:
 Kila darasa linatumia karatasi 200 x 5 = <<200*5=1000>>1000 kwa wiki.
Hivyo, kuna darasa 9000/1000 = <<9000/1000=9>>9 shuleni.
