Question

Mahukona is a Hawaiian volcano whose elevation is -3600 feet. Once, the volcano had an elevation of 200 feet. By how much has the elevation changed?

Answer 1

First, you want to get the absolute value of -3600 which is done by removing the negative so the absolute value is 3600.

Next, add 200 to 3600 to get your answer which is 3800.

So, the elevation has changed 3800 feet.

Hope this helps
