Question

If a chef planning for a large banquet thinks 2 out of every 5 dinner guests will order his soup appetizer. He expects 800 guest at the banquet. Use equivalent ratios to estimate how many cups of soup he should prepare.

Answer 1

320 cups

Explanation:

Assuming each guests uses only one cup of soup, the probability of getting a guest who needs a cup of soup is given as 2/5. Out of 800 people, then we expect 2/5*800=320 people who will need soup. Since we're assuming a cup of soup for each person then then the total amount of soup will be 320 people *1 cup=320 cups.

Therefore, you require 320 cups of soup for the guests.
