keeping in mind that 9 months is not even a year, since there are 12 months in a year, then 9 months are 9/12 year, or 3/4 of a year.


\bf \qquad \textit{Simple Interest Earned Amount}\\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\to& \$300\\ r=rate\to 2.5\%\to (2.5)/(100)\to &0.025\\ t=years\to (9)/(12)\to &(3)/(4) \end{cases} \\\\\\ A=300\left( 1+0.025\cdot (3)/(4) \right)
