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

### Instruction:
 Katika nyumba yenye watu 15, 3/5 ya watu hula pizza. Ikiwa Aviana alileta pizza zenye vipande 50, na kila mtu anayekula pizza alikula vipande 4, hesabu idadi ya vipande vya pizza vilivyosalia.


### Response:
 Ikiwa kuna watu 15 katika nyumba, idadi ya watu wanaokula pizza ni 3/5*15 = <<3/5*15=9>>9 watu.
Ikiwa kila mwanakaya anayekula pizza alikula vipande vinne, idadi ya vipande vilivyokuliwa ni 4*9 = <<4*9=36>>36 vipande.
Kwa kuwa jumla ya vipande vilikuwa 50, idadi ya vipande vilivyosalia ni 50-36 = <<50-36=14>>14 vipande.
