Explanation:

Step1: Recall balance - interest formula

The balance $B$ in a savings - account with simple interest is given by $B = P+I$, where $P$ is the principal (initial investment) and $I$ is the interest.

Step2: Identify values of $P$ and $I$

We know that $P = 520$ (initial investment) and $I = 42.64$ (interest).

Step3: Calculate the balance

$B=520 + 42.64=562.64$

Answer:

$562.64$
