$\bf ~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$4000\\ P=\textit{original amount deposited}\dotfill & \$2000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &10 \end{cases} \\\\\\ 4000=2000(1+r\cdot 10)\implies \cfrac{4000}{2000}=10r+1\implies 2=10r+1 \\\\\\ 1=10r\implies \cfrac{1}{10}=r\implies 0.1=r\implies \stackrel{\textit{converting to percentage}}{0.1\cdot 100\implies }~~\stackrel{\%}{10}=r$
