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

### Instruction:
 Chantal anakniti sweta za kuuza. Kila sweta inahitaji mpira wa kushona 4. Kila mpira wa kushona gharama $6. Chantal atapata pesa ngapi kwa jumla kwa sweta 28 ikiwa atauza kila sweta kwa $35?


### Response:
 Sweta 28 zinahitaji mpira wa kushona 28 x 4 = <<28*4=112>>112.
Hivyo, Chantal atatumia 112 x $6 = $<<112*6=672>>672 kwa jumla kwa mpira wa kushona.
Mapato yake yote kwa kuuza sweta 28 ni $35 x 28 = $<<35*28=980>>980.
Hivyo, Chantal atapata $980 - $672 = $<<980-672=308>>308.
