**Reiny**, Tuesday, November 9, 2010 at 11:36pminterest for lower rate loan = 7000(1.1)^n - 7000

interest for higher rate loan = 10080(1.12)^(n-.5) - 10080

10080(1.12)^(n-.5) - 10080 = 7000(1.1)^n - 7000

10080(1.12)^(n-.5) = 7000(1.1)^n - 7000 + 10080

1008(1.12)^(n-.5) = 700(1.1)^n + 308

no easy way to solve for n

I would try some values of n, until

left side = appr. right side
