At the Laika Boss Kennel Club, there are 15 dogs that are hairy or small, 2 dogs that are hairy and small, and 9 dogs that are small. How many dogs are hairy?

8 hairy dogs

Step-by-step explanation:

There are 15 dogs that are hairy or small

2 that are hairy and small

9 that are small

small - (hairy and small) = just small

9 - 2 = 7 small only dogs

Take the total dogs minus the small dogs minus the small and hairy dogs to find the hairy dogs

15 - 7 - 2 = 6

There are 6 hairy dogs

2 small and hairy dogs

7 small dogs

total 15 dogs

If we want the total of the hairy dogs

2 small and hairy + 6 hairy = 8 hairy dogs
