Marly is making soup. He adds 2 quarts of milk and three times as much chicken stock to 1 quart of pureed vegetables. Then he divides the soup into bags that can hold 3 quarts each. How many bags does he need?
First triple the amount of milk to find the amount of chicken stock: 2 quarts * 3 =

<output>6</output>
6 quarts.
Then add all three quantities to find the total volume of the soup: 6 quarts + 2 quarts + 1 quart = 
<gadget id="calculator">6+2+1</gadget>
<output>9</output>
9 quarts.
Finally, divide the number of quarts by the number of quarts per bag to find the number of bags needed: 9 quarts / 3 quarts/bag = 
<gadget id="calculator">9/3</gadget>
<output>3</output>
3 bags.
