Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did

In-s [12.5K]

$\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\to &\$450\\
P=\textit{original amount deposited}\to& \$3000\\
r=rate\to r\%\to \frac{r}{100}\\
t=years\to &3
\end{cases}
\\\\\\
450=3000\cdot r\cdot 3\implies \cfrac{450}{3\cdot 3000}=r\implies \cfrac{1}{20}=r
\\\\\\
r\%\implies \cfrac{1}{20}\cdot 100\implies r=\stackrel{\%}{5}$
