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

### Instruction:
 Faith alikwenda dukani la kuuza mikate na kununua unga uliogharimu $5 na kikombe cha keki kilichogharimu $28. Kisha akampa muuzaji pesa mbili za $20 na $3 kwa sarafu. Atapokea pesa ngapi kama mabadiliko?


### Response:
 Faith anapaswa kulipa $28 + $5 = $<<28+5=33>>33 kwa unga na kikombe cha keki.
Pesa zake mbili za $20 zinafikia $20 x 2 = $<<20*2=40>>40.
Kwa hivyo, alimpa muuzaji jumla ya $40 + $3 = $<<40+3=43>>43.
Hivyo, mabadiliko yake yatakuwa $43 - $33 = $<<43-33=10>>10.
