See a solution process below:

First, you can ignore the $387$ $387$ feet descent. It provides no useful information to this problem.

He ascent leaves Patrick at an elevation of:

$418 feet + 94 feet = 512 feet$ $418" feet " + 94" feet" = 512" feet"$

The second descent leaves leaves Patrick at an elevation of:

$512 feet - 132 feet = 380 feet$ $512" feet " - 132" feet " = 380" feet"$
