You need a 35-year, fixed-rate mortgage to buy a new home for $245,000. Your mortgage bank will lend you the money at a 5.40 percent APR for this 420-month loan. However, you can afford monthly payments of only $850, so you offer to pay off any remaining loan balance at the end of the loan in the form of a single balloon payment.

How large will this balloon payment have to be for you to keep your monthly payments at $850? (Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))
