Solve with Excel and show formulas please :)

Use a spreadsheet to set up a graduated payment mortgage that amortizes a $95,000 loan over 20 years with annual nominal payments increasing at 3% per year. Assume that nominal interest rates are 6.5% and general inflation is 3.5%.

a. Show that the debt is paid off at the end of the 20th payment.

b. Add two extra columns that show the level of real debt balances (in current dollars) and real payments (in current dollars). Generate two plots contrasting (a) the nominal vs real debt balances and (b) the nominal vs real payments.
