Final answer:
Devon needs to prepare 37.5 liters of soup for 100 guests by multiplying the amount of soup per person (375 milliliters) by the number of guests and converting the result from milliliters to liters.
Step-by-step explanation:
Devon works for a catering company and is calculating the necessary inventory for soup for a party with 100 guests. For each guest, she makes 375 milliliters of soup. To convert milliliters to liters, we use the conversion factor that 1,000 milliliters is equivalent to 1 liter.
To find out how much soup Devon will be making for the party, we multiply the quantity needed per person by the number of guests:
375 milliliters/person × 100 guests = 37,500 milliliters
Then we convert milliliters to liters:
37,500 milliliters ÷ 1,000 milliliters/liter = 37.5 liters of soup.
Therefore, Devon needs to have 37.5 liters of soup on hand for the kitchen to serve 100 guests.
