How many 1pound bags of trial mix should mary buy to have enough trial mix without leftovers

To determine the number of 1-pound bags of trail mix Mary should buy without having any leftovers, we need to know how much trail mix she requires.

Assuming Mary needs exactly 1 pound of trail mix, she should purchase 1 bag of 1-pound trail mix. If she needs 2 pounds, she should buy 2 bags, and so on.

Therefore, the number of 1-pound bags of trail mix Mary should buy depends on the quantity of trail mix she needs.
