Sagot :

Answer:

40people

Step-by-step explanation:

Let the number of those that owned a dog be x

Let the number of those that owned a cat be y

If the number of people who own a dog is four times the number of people who own a cat, then:

x = 4y

Since x+y =100

4y+y = 100

5y = 200

y = 200/5

y = 40

x = 4(40)

x = 160

Hence 40 people surveyed own a cat
