WE know that


A=Pe^(rt)

where A is the future value including interest, P is the the initial deposit, r is the annual interest rate and t is the time. Then in our case


\begin{gathered} A=300e^((.01)(3))^{} \\ =309.1 \end{gathered}

Then after three years we have 309.1. Substracting the initial deposit, we see that we earned 9.1 dollars.
