Answer 1

To determine which situation results in a change that could be modeled by a positive number, we need to calculate the changes in elevation for each option:

1. A change in elevation from **632 feet to 312 feet**:
Change = 312 - 632 = -320 (negative change)

2. A change in elevation from **–12 feet to 123 feet**:
Change = 123 - (-12) = 123 + 12 = 135 (positive change)

3. A change in elevation from **sea level to -87 feet**:
Change = -87 - 0 = -87 (negative change)

4. A change in elevation from **492 feet to -783 feet**:
Change = -783 - 492 = -1275 (negative change)

The only situation that results in a positive change is:

**a change in elevation from –12 feet to 123 feet.**
