QUESTION:

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% of the initial intensity \(I_{0}\) of the incident beam. What is the intensity of the beam 15 feet below the surface?
