[tex]\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$590\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\dotfill &3 \end{cases} \\\\\\ I=(590)(0.04)(3)\implies I=70.8[/tex]

Based on the amount deposited and the simple interest rate earned, the amount of interest earned will be $70.80.

Amuel deposited $590 into an account and this account earns 4% every year. This amount in dollars is:

= 590 x 4%

= $23.60

If he earned this amount every year, the amount he would earn in 3 years is:

= 23.60 x 3

= $70.80

In conclusion, Amuel would have made $70.80 in 3 years.
