Problem 2

The bar graph and picture graph both show the same data—the number of different animals seen in a park.

<p>Bar graph. Animals in the Park. Vertical axis labeled number of animals from 0 to 50 by fives. Horizontal axis labeled squirrel, duck, sparrow, swan. Height of bar: squirrel, 45. duck, 25. sparrow, 20. swan, 5.</p>

  1. How many squirrels and sparrows were seen altogether? Explain or show your reasoning.
  2. How many more squirrels were seen than sparrows and swans combined? Explain or show your reasoning.
