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

### Instruction:
 Preston ana duka la sandwich. Anachaji $5 kwa kila sandwich. Pia anachaji $20 kwa ada ya kusafirisha. Kampuni ya Abra inaagiza sandwich 18 kutoka kwa Preston na pia inampa bahasha ya 10%. Preston alipokea jumla ya kiasi gani, kwa dola?


### Response:
 Sandwich inagharimu $5 kila moja hivyo sandwich 18 inagharimu 5*18 = $<<5*18=90>>90.
Pia anachaji ada ya kusafirisha ya $20.
Jumla ya gharama, kabla ya bahasha, ni 90+20 = $<<90+20=110>>110.
Bahasha ni 10% hivyo inakuwa .10*110 = $<<10*.01*110=11>>11.
Jumla ni 110+11 = $<<110+11=121>>121.
