Question 1149572: The intensity of light under water decreases by 3.5% for every meter one descends. The function y=100(0.975) raised to x shows the relationship between the depth in meters (x) and the percent of surface light intensity that reaches the depth. Estimate the percent of light intensity that reaches the depths of 15 meters and 85 meters.

You can put this solution on YOUR website!
Two of your numbers are inconsistent. Either one is a typographical error, or the problem is flawed.
It is either a 3.5% decrease per meter with a function y = 100(0.965)^x, or a 2.5% decrease per meter with a function of y = 100(0.975)^x.
Re-post with consistent information.
Better yet, since there is nothing about this problem that we can help you with in terms of HOW to find the answer, determine the correct function and use a calculator to find the answers yourself.
