The variable x could represent the number of bottles of water sold.
The variable x could represent the total sales amount for the bottled water.
The variable y could represent the total sales amount for the hamburgers.
The variable y could represent the number of hamburgers sold.
The system of equations that could represent the concession sales is
2.50 x + 5.50 y = 1,325. x + y = 350.
The system of equations that could represent this situation is
x + y = 1,325. 2.50 x + 5.50 y = 350.
