While hiking, Tammy went up 200 feet. If Tammy started at 200 feet below sea level, which integer represents her elevation now?

Answer:

Since Tammy started from below sea level, so the position of Tammy can be taken as negative.

Tammy started from = - 200 feet

Tammy went up = 200 feet

Her current position is given by (- 200) + 200.

To find this, start with 200 and move 2 steps right as the gap between 2 steps is 100.



After moving, we reach at 0, so (- 200) + 200 = 0 feet i.e. at sea level.
