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

### Instruction:
Bert's golden retriever has grown tremendously since it was a puppy.  At 7 weeks old, the puppy weighed 6 pounds, but doubled in weight by week 9.  It doubled in weight again at 3 months old, and doubled again at 5 months old.  Finally, the dog reached its final adult weight by adding another 30 pounds by the time it was one year old.  What is the dog's full adult weight, in pounds?

### Response:
 Akiwa na umri wa wiki 7, mwana-kondoo alikuwa na uzito wa pauni 6, lakini uzito wake uliongezeka mara mbili kufikia wiki ya 9 na kufikia uzito wa pauni 6*2=<<6+6=12>>12.
Uzito wake uliongezeka mara mbili tena alipokuwa na umri wa miezi 3 na kufikia uzito wa pauni 12*2= <<12*2=24>>24.
Uzito wake uliongezeka mara mbili tena alipokuwa na umri wa miezi 5 na kufikia uzito wa pauni 24*2= <<24*2=48>>48.
Na alifikia uzito wake kamili wa watu wazima kwa kuongeza pauni nyingine 30 na kufikia uzito wa mwisho wa pauni 48+30= <<30+48=78>>78.
