Derek the blue monkey-man threw a pizza party. The Venn diagram shows how many friends ate which flavors of pizza.
Questions:
Hint: The numbers you see in the Venn diagram tell you how friends ate only pepperoni pizza, or only cheese pizza, or both; the number outside the circles tells you how many friends that didn't eat pizza. Don't forget that you must add the number of friends that ate both flavors to each number of friends that ate only one flavor.
