In January, Bill's labrador puppy weighs 40 pounds and his dachshund puppy weighs 12 pounds. Each dog gains 25% of their starting weight over the year. What's the difference in their weight at the end of the year? Give me reasons, before answering the question

First find how much weight the labrador puppy gains: 40 pounds * 25% = 10 pounds. Then add that weight gain to the puppy's starting weight: 40 pounds + 10 pounds = 50 pounds. Then find how much weight the dachshund puppy gains: 12 pounds * 25% = 3 pounds. Then add that weight gain to the puppy's starting weight: 12 pounds + 3 pounds = 15 pounds. Then subtract the dachshund puppy's weight from the labrador puppy's weight to find the difference: 50 pounds - 15 pounds = 35 pounds. So the final answer is 35.
