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

### Instruction:
 Bili ya chakula cha jioni kwa marafiki 6 ilikuwa $150. Silas alisema atalipa nusu ya bili na marafiki wengine waliobaki wanaweza kugawana bili iliyosalia na kuacha asilimia 10 ya chakula kama bahshishi. Marafiki watalipa kiasi gani kila mmoja?


### Response:
 150/2 = <<150/2=75>>75 dola zililipwa na Silas.
Bili iliyolipwa na marafiki waliobaki ilikuwa 150 - 75 = <<150-75=75>>75 dola.
Bahshishi ilikuwa dola 10/100*150 = <<10/100*150=15>>15
Marafiki walilazimika kulipa 75 + 15 = <<75+15=90>>90 dola
Kila mtu atalipa 90/5 = <<90/5=18>>18 dola
