Ok, I've got this problem: 
Now, this is the function for the air pressure x km above sea level. p is messured in mm Hg (milimeters)
Question is, calculate how high above sea level are we when the pressure is 700 mm Hg.
As you can see, this is equations with natural log, ln
The answer is supposed to be: 658 m, but I can't figure out the way to the answer :S
Need help with this one, please Detailed step by step answer would be lovable!
(Guess I put 700 for x in p(x), right?) But after that....
