Question

In a survey of 158 pet owners, 66 said they own a dog, and 89 said they own a cat. 22 said they own both a dog and a cat. How many owned neither a cat nor a dog?

Answer 1

Answer:

  25

Step-by-step explanation:

66 - 22 = 44 own a dog, but not a cat

89 - 22 = 67 own a cat, but not a dog

The number that own a dog, cat, or both is ...

  44 + 67 + 22 = 133

So, the number that own neither is ...

  158 - 133 = 25
