The formula to find the APY is
[tex]APY=(1+\frac{r}{n})^n-1[/tex]Being r the interest rate and n the number of times the interest is compounded per year
In our case
r=0.039
n=365
Replacing
[tex]\begin{gathered} APY=(1+\frac{0.0439}{365})^{365}-1 \\ \\ APY=0.04875 \\ \\ APY=4.88\% \end{gathered}[/tex]To know what this means we need the APY definition
APY stands for annual percentage yield, otherwise called effective annual rate (EAR). This measurement is used to estimate the potential gain from an investment or the final balance in a deposit account.
Answer: So we going to have a potential gain of 4.88%.
