Need help plz

 

At my office, 16 people own cats, people own dogs, and people own both cats and dogs.  How many people own a cat or a dog?

 

(Remember that in mathematics, the word "or" is used in the inclusive sense.  So if you own both a cat and a dog, then you are included in the category of people "who own a cat or a dog".)
