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

### Instruction:
 Katika San Diego Zoo, simba hula kilo 25 za nyama, na chui hula kilo 20 za nyama kwa siku. Ikiwa wana kilo 90 za nyama, nyama hizo zitadumu kwa siku ngapi?


### Response:
 Matumizi ya kila siku ya nyama ya simba na chui ni kilo 25 + 20 = <<25+20=45>>45.
Hivyo, ugavi wao wa nyama utadumu kwa siku 90/45 = <<90/45=2>>2.
