conversations.value: Bill's roof can bear 500 pounds of weight. If 100 leaves fall on his roof every day, and 1000 leaves weighs 1 pound, how many days will it take for his roof to collapse?

conversations.value: First, find how many leaves the roof can hold: 500 pounds * 1000 leaves/pound = 500000 leaves
  Then divide that by the number of leaves that fall each day to find how many days before the roof collapses: 500000 leaves / 100 leaves/day = 5000 days
