A mortgage contract for $48,200 written 10 years ago is just at the end of its second five-year term. The interest rates were 8% compounded semiannually for the first term and 7% compounded semiannually for the second term. If monthly payments throughout have been based on the original 25-year amortization, calculate the principal balance at the end of the second term assuming the amortization period of 20 years on renewal after the first five years.
