![When a vertical beam of light passes through a transparent medium, the rate at which its intensity \( I \) decreases is proportional to \( I(t) \), where \( t \) represents the thickness of the medium (in feet). In clear seawater, the intensity 3 feet below the surface is 25.3% of the initial intensity \( I_0 \) of the incident beam. What is the intensity of the beam 11 feet below the surface? (Give your answer in terms of \( I_0 \).
