Tamara is a marine photographer who wants to photograph marine life on a coral reef 21 m below the surface. She knows that the light intensity reduces by 2% for each metre below the water surface. It is a bright, sunny day, so the intensity of light at the surface is 100%.

Write an equation that models I(n) , the intensity of light, in
percent, n metres below the surface of the water. b) Tamara’s camera
requires a minimum of 67% of the light at the surface to operate
without an additional light source. Will she need the additional light
source at 21 metres?
