Bank B is better.

Bank A (simple): I = 2000(0.085)(10) = 1700, so total = 2000 + 1700 = $3,700.
Bank B (compounded annually): A = 2000(1.08)^10 ≈ 2000(2.158924997) ≈ $4,317.85.

So choose: "Bank B is the better investment. In 10 years, her $2,000 will grow to $4,317.85, and with bank A, her $2,000 will grow to $3,700."
