Using compound interest formula:

Where:

A = Amount

P = Principal = 8200

r = Interest rate = 6% = 0.06

n = Number of times interest is compounded per year = 2

t = time = 5

so:

$\begin{gathered} A=8200(1+(0.06)/(2))^(2\cdot5) \\ A=11020.11 \end{gathered}$

Therefore, the interest is the amount minus the amount invested:

$\begin{gathered} I=A-P \\ I=11020.11-8200 \\ I=2820.11 \end{gathered}$

Answer:

$2820.11
