Explain your thinking. about ry a word problem with Adding and Subtracting!

Lin went hiking on five different weekends. If Lin starts at an elevation of 768 feet and changes -96 feet. Where will her final elevation be?

1 answer

To solve this word problem, we need to add and subtract the given values correctly.

Given:
Starting elevation = 768 feet
Change in elevation = -96 feet

To determine Lin's final elevation, we need to subtract the change in elevation from her starting elevation.
This can be represented as:
Final elevation = Starting elevation - Change in elevation

Substituting the given values into the equation, we have:
Final elevation = 768 feet - (-96 feet)

When subtracting a negative number, it is equivalent to adding its positive counterpart. Therefore, the equation simplifies to:
Final elevation = 768 feet + 96 feet

Calculating the sum, we find:
Final elevation = 864 feet

Therefore, Lin's final elevation after the change of -96 feet will be at an elevation of 864 feet.
