Answer:
1.8 billion livres
Explanation:
As of 1683 following the death of King Louis XIII, the debt of the royal family stood at 200 million livres. However, by 1715 after the death of King Louis XIV. The debt of the royal family alone excluding the one owed by the previous king (200 million livres) stood at a whopping 2 billion livres.
Hence, the difference in the debt in millions of livres between 1683 and 1715 is 2 billion livres MINUS 200 million livres. That's equal to 1.8 billion livres.
