Some of these questions are really bad. It's unclear what's being asked for, in this problem the smart thing to do would be buying 1 pack of hot dogs and 2 packs of buns. And saying she does not want to have any food left over makes it even more confusing because this answer creates a ludicrous amount of leftovers.

The ones about cookies are poorly worded as well.
