Oceanography: The function y=20(0.975)^x models the intensity of sunlight beneath the surface of the ocean. The output y represents the percent of surface sunlight intensity that reaches a depth of x feet. The model is accurate from about 20 feet to about 600 feet beneath the surface.
Find the percent of sunlight 50 feet beneath the surface of the ocean.

• 5.6% of the sunlight

• 61% of the sunlight

• 15% of the sunlight

• 26.1% of the sunlight

Which equation matches the graph?

• y=2(2)^x

• y=2(1/2)^x

• y=2^x

• y=1/2(2)^x
