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

### Instruction:
 Johannes ana duka la mboga, anauza kabichi kwa $2 kwa kilogramu. Ikiwa Johannes alipata $30 Jumatano iliyopita, $24 Ijumaa iliyopita, na $42 leo, aliuza kilogramu ngapi za kabichi?


### Response:
 Jumatano iliyopita, Johannes aliuza kilogramu $30 / $2 = <<30/2=15>>15 za kabichi.
Ijumaa iliyopita, Johannes aliuza kilogramu $24 / $2 = <<24/2=12>>12 za kabichi.
Na leo, Johannes aliuza kilogramu $42 / $2 = <<42/2=21>>21 za kabichi.
Kwa hiyo, Johannes aliuza jumla ya kilogramu 15 + 12 + 21 = <<15+12+21=48>>48 za kabichi.
