The correct response is −48.5 ft.
To find the diver's elevation when he is 23% of the way down, we can multiply the distance of the treasure below the surface by 23%.
97.2 feet x 23% = 22.356 feet
Since the diver is descending, the elevation would be negative.
Therefore, the diver's elevation when he is 23% of the way down is -22.356 feet, which can be rounded to -22.4 feet or negative 22 point 4 feet.
To find the diver's elevation when he is 23% of the way down, we need to find 23% of 97.2 feet.
To calculate this, we can use the formula:
23% * 97.2 feet = (23/100) * 97.2 feet = 0.23 * 97.2 feet
Multiplying 0.23 by 97.2 gives us:
(0.23) * 97.2 = 22.356 feet
Therefore, the diver's elevation when he is 23% of the way down is 22.356 feet. Since the diver is going down, the elevation will be negative. Therefore, the answer is:
-22.356 feet (rounding to the nearest tenth)
So, the correct answer is:
negative 22.4 (rounded to the nearest tenth) ft.
