Answer 1

The highest point in a state park is 145 feet above sea level and the lowest point is 28 feet below sea level.

Therefore, the level below the sea level is considered negative, thus the difference in their elevations is given by:

The highest point in a state park-the lowest point below sea level

145-(-28)=145+28=173 feet.
