Sally begins hiking at an elevation of 224 feet. Then, she descends 131 feet and climbs 67 feet higher than her current position

Deffense [45]

Answer:

-3

Three feet below the initial elevation

Step-by-step explanation:

The initial elevation is 224 feet.

We take descent to be negative and ascent to be positive.

The numerical addition expression is

$224+-131+67+-163$

We simplify this to obtain:

$224-131+67-163=-3$

The negative sign means Sally is 3 feet below his initial elevation
