Final answer:
Without specific constraints on the tickets sold, such as prices and a maximum total, we cannot create a system of inequalities. Additional context is needed to accurately represent the scenario with inequalities.
Step-by-step explanation:
If s represents the number of student tickets and a represents the number of adult tickets, to represent the number of tickets sold, a system of inequalities is required. However, the information provided in the references does not give specifics regarding the constraints on ticket sales such as maximum capacity, budget constraints, or specific limits on the number of student or adult tickets. Therefore, without additional context or constraints, it is not possible to formulate an accurate system of inequalities.
What we can discern from the provided references is similar to budget constraints in consumer choice theory, where Alphonso has to make a decision between spending on burgers or bus tickets within his budget. A similar approach can be applied to ticket sales, where, for example, a certain budget could constrain the total revenue from student and adult tickets sold, resulting in a linear inequality representing that constraint.
In the context of the student's question, we would need additional information such as prices of tickets and the total available budget or number of seats to set up a viable system of inequalities.
