Respuesta :

The correct options are:

The elevation is 15,976 feet

A good expression would be 18,492 + -2,516

What is the elevation?

When a person goes up a mountain, the sign used to represent their height above sea level is a positive sign (+). When a person goes down a mountain, the sign used to represent their height above sea level is a negative sign (-). So, the sign in front of 18,492 would be positive and the sign in front of 2516 would be negative.

The expression that can be used to evaluate the elevation of the second campsite :

height of the first campsite - feet descended

18,492 - 2,516 =  15,976 feet
