The answer for this question is 4.74%,

the formula for this question is

f=(1+i)^m

=total - 1

I know that j=4.25%

m=2

i=j/m=.0425/2=.02125=2.125%

f=(1+.02125)^2 -1

=0.042951562

=4.30%

but the right answer is 4.74%, i cant seem to figure out how to get that answer.

**Reiny**, Saturday, March 27, 2010 at 7:35pmyou had an effective annual rate of

.042951563 which I agree with.

didn't it say they wanted to increase that effective rate by .5% or by .005

so .04295 + .005 = .04795 = 4.795%

(So I guess I disagree with their answer)
