Final answer:
Pilar will need 3 jars to store her 6 quarts of orange marmalade, with 2 quarts of marmalade in each jar.
Step-by-step explanation:
To determine the number of jars Pilar needs, we simply divide the total amount of orange marmalade she made by the capacity of each jar. Pilar made 6 quarts of marmalade and plans to put 2 quarts into each jar. Therefore, the number of jars needed is calculated as follows:
6 quarts ÷ 2 quarts per jar = 3 jars
Thus, Pilar will need 3 jars to store all the marmalade.
