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

### Instruction:
 Sheila, Purity, na Rose wanataka kukodi nyumba. Sheila amekubali kulipa mara tano ya sehemu ya Purity ya kodi. Rose anaweza tu kumudu mara tatu ya kile Purity analipa. Ikiwa sehemu ya Rose ni $1,800, kodi ya nyumba nzima ni kiasi gani?


### Response:
 Purity atalipa thuluthi ya sehemu ya Rose, ambayo inalingana na 1800 / 3 = <<1800/3=600>>600 dola.
Sheila amekubali kulipa mara tano ya sehemu ya Purity, ambayo inalingana na 600 * 5 = <<5*600=3000>>3000 dola.
Kodi ya jumla itakuwa 600 + 3000 + 1800 = <<600+3000+1800=5400>>5400 dola.
