Explanation:

To calculate the value of an amount of money invested with compound interest, use the formula:

$A = P {\left(1 + \frac{R}{100}\right)}^{n} \text{ or } A = P {\left(1 + r\right)}^{n}$

Where $R$ = rate of interest as a percent.
and $r$ = rate of interest as a decimal.

$A = 2000 {\left(1 + 0.05\right)}^{4}$

$A = 2000 {\left(1.05\right)}^{4} \text{ }$you have to use a calculator here.

A = \$2431.01
