Final answer:
The soup recipe serves 1 person per 10 cups. For 100 guests, Devon will need to make 37.5 liters of soup, given that she requires 375 milliliters per person.
Step-by-step explanation:
The recipe for the soup indicates that it makes 10 cups for 1 serving. Therefore, it serves 1 person per 10 cups.
Regarding Devon's catering for a party of 100 guests, she requires 375 milliliters of soup per person. Multiplying the amount per person by the number of guests gives:
- 375 milliliters/person × 100 persons = 37500 milliliters.
To convert milliliters to liters, since 1 liter is equivalent to 1000 milliliters, divide the total milliliters by 1000:
- 37500 milliliters / 1000 = 37.5 liters.
Therefore, Devon will be making 37.5 liters of soup for the party.
