Examine this map to help you respond to the question: What is the most likely elevation of point B? 105 feet 125 feet 80 feet 75 feet

Most likely either 105 ft or 80 ft. If I had to choose between those two I would probably choose 80 ft however.
If we look closely, we can see each line represents 25 feet. So, point b is between the 75 and 100 line. Therefore it is most likely to be 80 ft.
