15 caps are needed so that she can earn $85 in an hour day.
The direct variation equation has the form y = kx, where k is the constant proportionality. It is a linear equation with two variables. In a coordinate plane, the direct variation graph is a straight line. A constant is the ratio of two quantities that vary directly. Relationship between two variables that can be described mathematically by an equation where one variable equals a constant multiplied by the other.
For each hour she is compensated $6.50 with $0.45.
For an 8 hour day =6.50 *8 + 0.45x
Let x be the caps and earning is $85
6.50*8+0.45*x=85
=> 52+0.45x=85
=> 0.45x=33
=> x=15 (approx.)

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:
