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

### Instruction:
George bought some food for his trip: a bottle of juice, a sandwich, and a bottle of milk. The sandwich was for $4, and the juice was two times more expensive. The bottle of milk cost was 75% of the total cost of the sandwich and juice. How much did George pay for his food?

### Response:
 Juisi ilikuwa mara mbili zaidi ya bei ya sandwichi, hivyo ilikuwa 4 * 2 = $<<2*4=8>>8.
Hivyo George alinunua juisi na sandwichi kwa 8 + 4 = $<<8+4=12>>12.
Gharama ya chupa moja ya maziwa ilikuwa 75/100 * 12 = $<<75/100*12=9>>9.
Kwa jumla, kwa chakula chote, George alilipa 12 + 9 = $<<12+9=21>>21.
