Sorry, but I think you've got a wrong answer instead of a problem of rounding the figure :|

anonymous · Answer

my formula is APY=prt+p

callisto · Answer

And I'm getting one of the answers in your choices..
Try to solve this:
amount = 613 x [1+ (3.4%/12)]^(12x7)

mertsj · Answer

$$A=P(1+\frac{r}{n})^{nt}$$

anonymous · Answer

oh ok I see my notes and I was solving for Apy WHEN i SHOULD SOLVE FOR exponential growth

mertsj · Answer

$$A=613(1+\frac{.034}{12})^{7(12)}$$
$$A=613(1.002833333333)^{84}=777.46$$
