A. There were 300 liters in the tank after 20 minutes, and it is
decreasing by 7 liters per minute.
O B. There were 300 liters in the tank when the leak started, and it is
decreasing by 7 liters per minute.
C. There were 7 liters in the tank when the leak started, and it is
decreasing by 300 liters per minute.
