Answer:

521 feet.

Step-by-step explanation:

In the given question, the number of feet covered with respect to climbing would have a positive value. While the number of feet descended would have negative value.

The total feet covered by Brody and Carrie, with the elevation of the trail-head should be equal to the elevation of their destination above sea level.

To determine the elevation of the trail-head, let its elevation be represented by h.

So that,

h + 103 - 84 + 194 = 734

h + 297 - 84 = 734

h + 213 = 734

h = 734 - 213

h = 521

h = 521 feet

The elevation of the tail-head is 521 feet.
