Answer:
8 hairy dogs
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
