Answer:
The answer is 379 people don't own dogs
Explanation:
keep in mind that the # of people surveyed are 692
1. plug in all the information we know
2. 448 birds in total, subtract 87, 106 and 163 from 448. We get 92.
3. 569 people own pets, 692 - 569 = 123, this means that 123 people own no pets
4. we take 569 and subtract it by all the numbers we have to get 34 people that own both fish and dogs but no birds
5. lastly, you add 87+106+63 to get 379
that is the amount of people with no dogs
