Step-by-step reasoning process: 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.

The answer is 35

Step-by-step reasoning process: Paige has 100 space stickers that she is dividing among 3 friends, so 100 stickers / 3 friends = 33 stickers for each friend, with 1 remaining. She also has 50 cat stickers that she is diving among 3 friends, so 50 stickers / 3 friends = 16 stickers for each friend, with 2 remaining. So Paige will have 1 remaining space sticker + 2 remaining cat stickers = 3 stickers left.
