I believe the APY would be $520 for the rounded version and $520.20 for the not rounded

(not completely certain since i didnt fully understand)

Explanation:

using the formula for calculating compounding semi annualy

A = P(1 + r)t

A= 500(1+0.02)2 (i put 2 instead of one year because its semi annually so twice)

A= 500(1.02)2

A= 500x1.04=$520(rounded)

A=500x1.0404= $520.20(not rounded)
