Margot's Gum Ball Collection

How many blue gum balls does Margot have in her bag?

Answer:

Margot has a total of 25 gum balls in her bag. Among them, she has 9 pink, 4 green, 3 yellow, 2 white, and the rest are blue gum balls.

To find out how many blue gum balls Margot has, we can subtract the total of other colored gum balls from 25.

So, 25 -(9 + 4 + 3 + 2) = 25 - 18 = 7 blue gum balls.

Therefore, Margot has 7 blue gum balls in her bag.
