Final answer:
To find the total sales amount for 2-liter containers, divide the total cost by the volume. The total sales amount for 2-liter containers on this particular day is 2 liters.
Step-by-step explanation:
To determine the total sales amount for 2-liter containers, we need to find out how many 2-liter containers can be bought with the given amount of money.
First, we need to calculate the price per liter by dividing the total cost by the volume: $4.50 / 2 liters = $2.25 per liter.
Next, we divide the amount of money available by the price per liter to find how many liters can be bought: $2.25 / 1 liter = 2 liters.
Therefore, the total sales amount for 2-liter containers on this particular day is 2 liters.
