A government starts off with a total debt of $5.5 billion. In year one, the government runs a deficit of $600 million. In year two, the government runs a deficit of $1.5 billion. In year three, the government runs a surplus of $400 million.

• What is the total debt of the government at the end of year three?
• Assuming the government runs a deficit of $200 million in year three, what is the total debt of the government at the end of year three?
• If a government runs a budget deficit of $5 billion dollars each year for ten years, then a surplus of $2 billion for five years, and then a balanced budget for another ten years, what is the government debt?
