    Barbara adds 1 link to her paper chain every day. Bill adds 3 links to his chain every day. Barbara's chain has 9 links right now, and Bill's chain has 3 links right now. If they keep adding links at the same rate,how many days before Bill's chain has exactly twice as many links as Barbara's chain?
