The intensity of light below the surface of a clear lake depends on many factors. One model shows that 11% of light is absorbed for each 1-meter increase in depth. Find an exponential model, P, for the percentage of light that reaches a depth of d meters. P(d) = Use your model to predict what percentage of light will reach a depth of 7 meters.
