1. I need six dozen 1¼" screws. They will cost me five cents a dozen. There are twelve dozen in a box, and a box will cost thirty-two cents. Would it pay me to get just what I need now?

2. All but three of the girls in our class are members of the United States School Garden Army. Edith is not a member of the United States School Garden Army. Is it possible that Edith is a member of our class?
