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

### Instruction:
Terry's mom brought home 4 different colored dogs from the shelter. The brown dog weighs 4 pounds. The black dog weighs 1 pound more than the brown dog. The white dog weighs twice as much as the brown dog. The grey dog weighs 2 pounds less than the black dog. What's the average weight of all the dogs?

### Response:
 Kwa kuwa mbwa mweusi ana uzito wa pauni 1 zaidi ya mbwa mweusi, mbwa mweusi ana uzito wa pauni 4 + 1 = <<1+4=5>>5.
Kwa kuwa mbwa mweusi ana uzito wa pauni 2 chini ya mbwa mweusi, mbwa mweusi ana uzito wa pauni 5 - 2 = <<5-2=3>>3.
Mbwa mweupe ana uzito wa pauni 4 * 2 = <<4*2=8>>8.
Uzito jumla wa mbwa wote ni pauni 4 + 5 + 3 + 8 = <<4+5+3+8=20>>20.
Uzito wastani wa mbwa wote ni pauni 20 / 4 = <<20/4=5>>5.
