So 15% is out of 100%, and the cab company has sent 30 cabs out of x?(x is the total number of cabs). 
So, by setting up that data we already know, we can make this equation to figure out how many cabs total the company actually has:
<span>15x = 100 * 30
</span>
We do the multiplication on the right side
15x = 3000
And divide to isolate the "X" variable
x = 200
So, the cab company has 200 cabs total, and they sent out 30 of them.

<u>Solution-</u>
The atmospheric pressure at sea level = 14.7 lb/in²
Pressure gets reduced by half for each 3.6 miles we move up.
Taking,
x = miles above the sea-level
y = pressure in lb/in²
0 14.7
3.6 7.35
7.2 3.675
10.8 1.8375
It can be observed that both the variables are in inverse proportion as the distance from sea-level increase the pressure decreases.
As only the second graph satisfies the points and inverse proportional condition, so that is the correct graph.
By plotting the graph in excel taking these data set, the following plot was obtained.
