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

### Instruction:
 Kiti kimoja kina gharama 1/7 ya gharama ya meza. Ikiwa meza inagharimu $140, itagharimu kiasi gani kununua meza na viti 4?


### Response:
 Kiti kimoja kinagharimu $140 x 1/7 = $<<140*1/7=20>>20.
Viti vinne vinagharimu $20 x 4 = $<<20*4=80>>80.
Hivyo, meza na viti 4 vitagharimu $140 + $80 = $<<140+80=220>>220.
