Answer:

Step-by-step explanation:

One

If there are 12 dogs and cats in the vet's office, then if they were the same, there would be 6 dogs and 6 cats. Since there are are more dogs than cats, the number of dogs would have to be at least 7 to get more cats than dogs. If there were 7 dogs, there could only be 5 cats so that the total would be 12.

Two

The question is becoming more general. The answer is C.  Notice that's exactly what happened in part one.
