Q: Milly and Floretta are having a water balloon fight in their garden. They use 3 packs of their own water balloons and also use 2 packs of a neighbor's water balloons. Each pack of water balloons contains 6 balloons. Milly and Floretta fill all of the balloons then split them evenly, but Milly takes an extra 7 balloons when Floretta isn't looking. How many water balloons is Floretta left with?
A: Milly and Floretta have a total of 3 packs of their own water balloons + 2 packs of the neighbor's water balloons = 5 packs of water balloons. So there is a total of 5 packs of water balloons * 6 balloons per pack of water balloons = 30 water balloons available. As they split them evenly, they each have 30 water balloons / 2 = 15 water balloons. After Milly steals some balloons, Floretta is left with 15 7 = 8 water balloons. The answer is 8.

Q: 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?
A:
At 7 weeks old, the puppy weighed 6 pounds, but doubled in weight by week 9 to reach a weight of 6 * 2 = 12 pounds. It doubled in weight again at 3 months old to reach a weight of 12 * 2 = 24 pounds. It doubled in weight again at 5 months old to reach a weight of 24 * 2 = 48 pounds. And it reached its full adult weight by adding another 30 lbs to reach a final weight of 48 + 30 = 78 pounds. The answer is 78.
