Find the interest if $ 9,000 is invested at an annual simple interest rate of 8 % for 3 years. Use the formula I = P × R × T , where I is the interest earnings, P is the principal, R is the annual rate and T is the time, expressed in years.
(a) $ 216,000 (b) $ 4,216.00 (c) $ 2,160 (d) $ 21.60 (e) $ 196.00

I = P × R × T
I = 9,000 * 0.08 * 3
I = ?
