First, we need to find the total amount of soup in all the containers:
Total amount of soup = number of containers * amount of soup in each container
Total amount of soup = 7 * 18
Total amount of soup = 126 ounces
Then, we divide the total amount of soup by the number of people:
Amount of soup per person = Total amount of soup / Number of people
Amount of soup per person = 126 / 9
Amount of soup per person = 14 ounces
Therefore, each person will get 14 ounces of soup...
