Final answer:
The student's question pertains to finding the number of reserve and general admission tickets sold at a football game based on the total sales amount and the price of each type of ticket, as represented by a linear equation.
Step-by-step explanation:
The student is asking about solving a linear equation that represents a real-world problem. The equation is 20x + 12y = 900, where x and y represent the number of reserve seats and general admission seats, respectively, at a football game.
The question is: How many reserve tickets (x) and general admission tickets (y) were sold if the total ticket sales were $900, with reserve tickets costing $20 each and general admission tickets costing $12 each?
To solve this, we would need another equation to have a system of equations because we have two variables. This could arise from having additional information such as the total number of tickets sold
