Final answer:
To calculate the amount of soup for the party, multiply the amount of soup per person by the number of guests. Devon will be making 37.5 liters of soup for the party.
Step-by-step explanation:
To calculate the amount of soup Devon will be making for the party, we need to multiply the amount of soup per person (375 milliliters) by the number of guests (100). First, we convert milliliters to liters by dividing by 1000. So, 375 milliliters is equal to 0.375 liters. Then, we multiply the amount of soup in liters (0.375) by the number of guests (100) to get the total amount of soup Devon will be making for the party.
In this case, Devon will be making 37.5 liters of soup for the party.
