Amarine biologist is setting up a net 6 feet below the surface of the water. each foot of the water screens out 40% of the light coming from the surface. which of the following is the approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent?

The correct answer is C. 4.7%

Correct statement and question:

A marine biologist is setting up a net 6 feet below the surface of the water. Each foot of the water screens out 40% of the light coming from the surface. Which of the following is the approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent?

0.4%

1.0%

4.7%

7.8%

Step-by-step explanation:

1. Let's review all the information given to us to answer the question correctly:

Depth of the net = 6 feet below the surface of the water

Each foot of the water screens out 40% of the light coming from the surface.

2. Which is the approximate percentage of light remaining after passing through 6 feet of water, to the nearest tenth of a percent?

After one feet: 100 - 40 = 60%

After two feet = 60 - 0.4 * 60 = 60 - 24 = 36

After three feet = 36 - 0.4 * 36 = 36 - 14.4 = 21.6

After four feet = 21.6 - 0.4 * 21.6 = 21.6 - 8.64 = 12.96

After five feet = 12.96 - 0.4 * 12.96 = 12.96 - 5.18 = 7.78

After six feet = 7.78 - 0.4 * 7.78 = 7.78 - 3.11 = 4.67 = 4.7 (Rounding to the nearest tenth)

The correct answer is C. 4.7%

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
