Final answer:
Amanda is 85 feet below her starting point after descending 330 feet and ascending a total of 245 feet.
Step-by-step explanation:
The student's question is about determining the final position of Amanda in relation to her starting point after several changes in elevation during her hike. To solve this, we add her upward movements and subtract her downward movements.
Firstly, Amanda descends 330 feet, then she ascends 120 feet and ascends another 125 feet. So, her total change in elevation is (-330) + 120 + 125 feet. To find out where Amanda is in relation to her starting point, we simply perform the arithmetic operation: (-330 feet) + 120 feet + 125 feet = -85 feet.
Therefore, Amanda is 85 feet below her starting point on the mountain after her hike.
