Answer:
Dani's family can foster either 0 Dogs/3 Cats, 1 Dogs/2 Cats, 2 Dogs/1 Cats, 3 Dogs/0 Cats
Step-by-step explanation:
The number of cats or dogs is directly proportional to the number of the opposite animal they hold, this is x + 3 = y , -x + 3 = y , -2x + 3 = y , -2x+ 3 = y.
This will show how as we add numbers of one of the options the other one reduces to keep a constant result of three which is the number of animals they can foster.
