Lizzy: The weights of Christine's two cats are 7 and 10 pounds. What is her dog's weight if its weight is twice the sum of her two cats' weights?.
Me: Hmmm, let me think. I think this is the detailed solution:
The sum of the weights of Christine's two cats is 7 + 10 = 17 pounds. Christine's dog weighs 17 x 2 = 34 pounds. Final answer: 34.
