Final answer:
The 'x' and 'y' variables in the system of equations represent different quantities, and in this scenario, 'x' represents the total revenue from adult tickets, and 'y' represents the total revenue from student tickets.
Step-by-step explanation:
The 'x' and 'y' variables in the system of equations represent:
A. x represents the price of an adult ticket, and y represents the price of a student ticket.
B. x represents the number of adult tickets sold, and y represents the number of student tickets sold.
C. x represents the total revenue from adult tickets, and y represents the total revenue from student tickets.
D. x represents the profit from adult tickets, and y represents the profit from student tickets.
In this scenario, option C is correct. In a system of equations, the variables 'x' and 'y' represent the unknown quantities that we are trying to find. In this case, 'x' represents the total revenue from adult tickets, and 'y' represents the total revenue from student tickets.
