Answer
Solution: C
The original monthly payment is
[[math]]85,000 /a_{\overline{240}|0.005}[[/math]]
. On July 1, 2009 there has been 4 years of payments, hence 16x12 = 192 remaining payments. The outstanding balance is
The number of remaining payments after refinancing is determined as
[[math]]
608.97a_{\overline{240}|0.005} = 608.97(123.2380) = 75, 048.24.
[[/math]]
The number of remaining payments after refinancing is determined as
[[math]]
\begin{array}{l}{{75,048.24=500a_{\overline{{{n}}}|0.0045}=500\frac{1-1.0045^{-n}}{0.67543=1-1.0045^{-n}}}}\\ {{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}}\\ {{n=-\ln(0.32457)/\ln(1.0045)=250.62.}}\end{array}
[[/math]]
Thus the final payment will be 251 months from June 30, 2009. This is 20 years and 11 months and so the final payment is May 31, 2030.
