Irene borrowed a loan of $1,000,000 at an interest rate of 5% amortized over
30 years by annual payments. The first 15 payments were made on time
but the next 3 were defaulted. A new agreement was then made to pay the
remaining obligation in 12 equal annual payments at 6%, the first payment
being made 1 year after the 3rd defaulted payment. Calculate the amount of
the principal repaid in the 6th rescheduled payment.
