I need help understanding the following two questions:1) The current U.S. National Debt is about 17.2 trillion dollars ($17,200,000,000,000). Use some or all of the information below to make sense of the National Debt, then type your answer to the questions below:In-State Kean University Tuition, Books, Fees, Room & Board (2012): $ 29,515Out-of-state Kean University Tuition, Books, Fees, Room & Board (2012): $ 35,557Median Price of a New Home Sold in United States (2010): $221,800Average Student Loan Debt for U.S. Undergraduates (2010):$ 25,119Median U.S. household income, (2007-2011) $ 52,762In your opinion, is the U.S. National Debt large or small? Can you describe how large or how small? Show any and all calculations you do below. Explain your reasoning as clearly as possible.2) Rhena’s salary is $45,000.00 a year at her first job, but unfortunately the bad economy results in all employees getting a 15% pay cut for 2011. Then in 2013 because things get better, everyone gets a 15% pay raise. Why is Rhena’s 2013 salary NOT $45,000.00 like it was before the pay cut in 2011?Explain and support your explanation with appropriate calculations!
