You need 4 cups of flour and 2 cups of sugar.

Can you bake cookies with 3 cups of flour and 2 cups of sugar?

A good answer might be:

No. You have enough sugar, but not enough flour, so you can't follow the recipe.

Both Items Needed

The question about whether you have enough supplies has two parts:

You need at least 4 cups of flour    AND    You need at least 2 cups of sugar

Since you do not have enough flour, you don't have enough supplies.


What if you had 9 cups of flour and 1 cup of sugar. Now could you follow the recipe?
