Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.
<h3>What is the exponential function for the oxygen levels?</h3>
The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:

In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:
