Answer:
6.95 pounds. Her dog weighs 6.95 more pounds than the total weight of both her cats.
Explanation:
To find the total weight of her cats, add their weights together:
9.8+8.25
=18.05 pounds
Then to find the difference between the weight of her dog and the weight of her cats' total weight, you subtract the weight of the cats from the weight of the dog:
25-18.05
=6.95 pounds
