You can afford $1400 per month to buy a house. You found a 30 year mortgage at 7% interest. How much total interest will you have to pay the bank after 30 years? (Hints: Use the number you calculated in the last question. Subtract the total amount of the mortage from the question before that. (Total money you pay the bank - amount of original loan) Answer to the nearest cent. Do not put a dollar sign.
