Some college students collected data on the intensity of light at various depths in a lake. Here are their data.

The exponential model used for the data was y = 1173. 882(0.695), where the depth in meters is the explanatory variable.
Use the model above to extrapolate what the light intensity would be at a depth of 20 meters. Round to the nearest hundredth.
