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

### Instruction:
Blanche, Rose and Dorothy liked to collect sea glass when they went to the beach.  Blanche found 12 pieces of green and 3 pieces of red sea glass.  Rose found 9 pieces of red and 11 pieces of blue sea glass.  If Dorothy found twice as many pieces of red glass as Blanche and Rose and three times as much blue sea glass as Rose, how many pieces did Dorothy have?

### Response:
 Blanche alipata vipande 3 vya kioo cha nyekundu na Rose alipata vipande 9 vya kioo cha nyekundu kwa jumla ya vipande 3+9 = <<3+9=12>>12 vya kioo cha nyekundu.
Dorothy alipata mara mbili ya vipande vya kioo cha nyekundu kama marafiki zake, hivyo alikuwa na vipande 12*2 = <<12*2=24>>24 vya kioo cha nyekundu.
Rose alipata vipande 11 vya kioo cha bluu na Dorothy alipata mara tatu ya kioo cha bluu kama Rose, hivyo alikuwa na vipande 11*3 = <<11*3=33>>33 vya kioo cha bluu.
Kwa pamoja, Dorothy alipata vipande 33 vya kioo cha bluu na 24 vya kioo cha nyekundu, hivyo alikuwa na vipande 33+24 = <<33+24=57>>57 vya kioo cha bahari.
