Given data,

\(\displaystyle{t}={7}\) years

\(\displaystyle{P}={2000}\)

\(\displaystyle{|}><={4}\%={0},{04}\)

\(\displaystyle{n}={2}\) (semi-anually)

\(\displaystyle{A}={P}{\left({1}+\frac{{{|}><}}{{n}}\right)}^{t}{n}\)

\(\displaystyle={2000}{\left({1}+\frac{{{0},{04}}}{{2}}\right)}^{{{2}+{7}}}\)

\(\displaystyle={2000}{\left({1}+{0},{02}\right)}^{14}\)

\(\displaystyle={2638},{96}\)

We get a finally answer

\(\displaystyle{A}=\${2639}\)

The amoun \(\displaystyle{a}{\mathtt{{|}}}><{7}\) years is $ 2639
