Question 4.

Sierra has 13 stuffed animals. Five of them are polar bears. The rest are penguins. How many penguins does Sierra have?

Answer:

8 penguins

Explanation:

Here Sierra has 13 stuffed animals in this 5 are polar bears. So by subtracting the number of stuffed animals with polar bears we can get the rest of the penguins. Hence the number of penguins Sierra has 13-5 = 8 penguins.
