Eli is making soup for his family. He adds 3 cups of vegetables, 4 cups of broth, 1 cup of chicken, and 2 cups of noodles to the soup. What percentage of the soup is vegetables?

A.300%
B.30%
C.3%
D.33

To find the percentage of the soup that is vegetables, we need to find the total number of cups in the soup.

3 cups vegetables + 4 cups broth + 1 cup chicken + 2 cups noodles = 10 cups total

Now we can find the percentage of vegetables by dividing the number of cups of vegetables by the total number of cups and multiplying by 100:

(3 cups vegetables / 10 cups total) * 100 = 30%

The percentage of the soup that is vegetables is 30%, so the answer is B. 30%.
