Use the picture below to find the distance between the point below sea level (-155) to the point above sea level (1025).
*

1180
870
The distance between the point below sea level (-155) to the point above sea level (1025) is given by the absolute difference of the two values:

|(-155) - 1025| = |-1180| = 1180

So, the correct answer is 1180.
9. Leah borrowed $20 from her brother. Which integer best represents how much money Leah owes?
