Ten years ago, George purchased a house for $200,000, with a 20% down payment and financed the rest for 30 years at a 0.4% per month interest rate with end-of-the-month payments. Today, George sold the house for $420,000. He must pay a Real Estate bill for 7% of the sale price to account for sales commission and other charges, and pay off the mortgage. How much cash is he left with after paying the bank and the Real Estate Bill?
