Question

In a survey of 85 pet owners, 10 said they own a dog, and 36 said they own a cat. 9 said they own both a dog and a cat? How many owned a dog but not a cat

Answer 1

- The formula to use to solve this question is:

`\text{ dog owners-dog and cat owners}`

- We have been given:

`\begin{gathered} \text{ dog owners}=10 \\ \text{ cat owners}=36 \\ \text{ cat and dog owners}=9 \end{gathered}`

- Thus, we can find the number of people that own just dogs as follows:

`10-9=1`

Final Answer

Only 1 person owns dogs only
