**Reiny**, Tuesday, June 26, 2012 at 8:13amamount after the first 2½ years

= 60000(1.035)^7

= 76336.756

I will assume that the rate for the remaining 1½ of 5.6% is also compounded semiannually

amount at end of 4 years

= 76336.756(1.028)^3

= 82930.26

**Reiny**, Tuesday, June 26, 2012 at 9:13amDon't know how I got 7 as the exponent in the first part

of course it should have been 5 ( for 5 half years in 2 1/2 years)

Please make the necessary corrections.
