Explanation:

Step1: Find number of students without dogs

We know the total number of students is 40 and the number of students who don't have dogs is 15.

Step2: Fill in known values for rows and columns

We know the total number of students with dogs is 40 - 15=25. Also, the number of students without dogs and without cats is 8. So the number of students without dogs and with cats is 15 - 8 = 7.

Step3: Use the given percentage to find more values

We are given that 40% of students who have dogs don't have cats. So the number of students with dogs and without cats is 0.4×25 = 10. Then the number of students with dogs and with cats is 25 - 10=15. The total number of students with cats is 15 + 7=22, and the total number of students without cats is 10 + 8 = 18.

Answer:

	Have Dogs	Don't Have Dogs	Total
Don't Have Cats	10	8	18
Total	25	15	40
