Answer:
Therefore, London will pay $575.00 for the soup.
Explanation:
There are 4 cups in 1 quart, so 1 quart can serve 4/3 = 1.33 people (approx.)
To serve 60 people, London needs 60/1.33 = 45.11 quarts of soup (approx.)
Since soup is sold in 1-quart containers, London needs to buy 46 quarts (to ensure enough soup)
The cost of each quart container is $12.50, so the total cost will be:
46 quarts x $12.50/quart = $575.00
Therefore, London will pay $575.00 for the soup.
