Final answer:
The overall vertical change of the commercial jet liner, calculated by adding the altitude gains and subtracting the losses, results in a vertical change of 77 feet. However, this result doesn't match any of the provided multiple-choice options.
Step-by-step explanation:
The overall vertical change of the commercial jet liner is calculated by subtracting the altitude loss from the altitude gain.
The initial climb was 184 feet. The plane then dropped 210 feet. Finally, it adopted an altitude of 103 feet, which is the positive vertical change from its last position.
To find the overall vertical change, we need to combine these changes. First, we add the gain and the final altitude: 184 feet + 103 feet = 287 feet. Then, we subtract the drop: 287 feet - 210 feet = 77 feet.
So, the overall vertical change is 77 feet. This is not one of the provided options, so it seems there might be a mistake in the question or the options given.
