Solve the problem.Sunlight is absorbed by water and so, as one descends into the ocean, the intensity of light diminishes. Suppose that at each depth, going down one more meter causes a 15% decrease in the intensity of sunlight.(a) Write the difference equation for yn, the intensity of the light at a depth of n meters.(b) If the intensity of the light at the surface is 500 units, what is the intensity of the light at a depth of two meters?(c) Graph the difference equation. 
What will be an ideal response?
| (a) | yn = 0.85yn-1 (b) 361.25 units |
