Jill invests $10000 in an account that pays an annual rate of 3.96%, compounding semi-annually. Approximately how much

$$U\sin g\ compound\ interest\ formular\ =>$$
$$Amount\ \left(A\right)\ =\ P\left(1+\frac{r}{n}\right)^{nt}$$
$$where\ A\ =\ amount\ =\ ??$$
$$\ p\ =\ principal\ =\ $10,000$$
$$\ r\ =\ rate=\ 3.96\%\ =\ 0.0396$$
$$n\ =\ number\ of\ times\ interest\ is\ compounded\ for\ this\ period$$
$$=2\cdot2=4\ \left(twice\ a\ year\ for\ 2\ years\right)$$
$$t\ =\ time\ =\ 2\ years$$
$$A=10000\left(1+\frac{0.0396}{4}\right)^{2\cdot4}$$
$$A=10000\left(\frac{4+0.0396}{4}\right)^8$$
$$A=10000\left(1.0099\right)^8$$
$$A=10819.99$$
$$which\ is\ approximately\ $10,820$$
$$The\ only\ option\ that\ suits\ this\ approximation\ is\ B$$
