How much interest is due on $3500 at 6^(3/4) % for nine months?
can anybody manipulate 6^ 3/4 % how is that possible?
I misread your amount of interest...
To compute the amount of interest due, use:
$\displaystyle I=P\left(\left(1+\frac{r}{n} \right)^{nt}-1 \right)$
where:
P = principal
r = annual interest rate
n = number of compounding periods per year
t = number of years
