Final answer:
The question applies mathematical operations to economic concepts, calculating equilibrium of demand and supply for pizzas at a certain price and determining the number of sandwiches that can be made with a fixed number of ingredients.
Step-by-step explanation:
The subject question relates to basic mathematical operations, specifically regarding producers supplying goods at a certain price point, and the concept of equilibrium where quantity demanded (Qd) equals quantity supplied (Qs).
It touches on mathematical principles applied to economics, where a scenario is given where at a price of $2 each, producers will supply 12 personal pizzas, indicating that the calculated demand and supply are equal.
Furthermore, the same principles can be applied to a situation with a fixed amount of resources, such as 28 slices of bread and 11 slices of cheese, from which one can determine the maximum number of sandwiches that can be prepared based on the limiting ingredient, which in this case is the cheese slices.
