Final answer:
Jillian's model for whipped cream per dessert bowl is proportional, showing a linear relationship. Devon would need 37.5 liters of soup for 100 guests, illustrating the practical application of stoichiometric relationships in everyday cooking.
Step-by-step explanation:
Jillian's use of whipped cream for her desserts follows a proportional model. This is because for each additional bowl of dessert she prepares, she will always use 3 tablespoons of whipped cream. The ratio of tablespoons of whipped cream to bowls of dessert is a constant rate, indicating a direct and consistent relationship between the two quantities. In mathematics, when each unit increase in one quantity results in a consistent unit increase in another, it is defined as a proportional or linear relationship.
Now, considering Devon's scenario at the catering company, to calculate the amount of soup needed for the party with 100 guests, we use the concept of conversion from milliliters to liters. As she makes 375 milliliters of soup per person, for 100 guests, she would need 375 milliliters x 100 guests = 37,500 milliliters of soup. Since there are 1,000 milliliters in a liter, Devon will need 37.5 liters of soup for the party.
The concept explained through these examples is fundamentally rooted in stoichiometric relationships that are used in chemistry as well as in common everyday activities such as cooking. These relationships help in scaling recipes, whether it's for making pancakes or salads, in proportion to the amount required.
