Of 350 students polled, some have a cat, some have a dog, and some have both. One hundred seventy-five students have a cat and 140 have both types of pets. How many students have a dog only? Explain.

I believe the answer was:

175; Since 175 have a cat or a cat and dog, then the number that have a dog only is 350 - 175 = 175.

But I just needed to check

    Total students 350

    350 - 175 cats = 175

    175 - 140 both pets = 35 dog only students

    I guess
