The solution will be: 
<em><u>Explanation</u></em>
The given inequality is: 
First we will subtract
from both sides. So.....

Now we will subtract 13 from both sides. So.....

Then we need to divide both sides by -3. As here we are <u>dividing the inequality by a negative number, so we need to switch the inequality symbol</u>. So, we will get.......

Thus, the solution will be: 
The answer would be in a coordinate plane between quadrant 2 and 3.
First of all we know the
Absolute Value Function that is:

This is called the
Parent Function <em>of the Absolute Value Function.</em>
From the equation:

The term:

means that the the Parent Function is <em>shifted</em>
two units <em>to the left</em>.
On the other hand, the term:

means that the function

is <em>shifted</em>
three units <em>downward. </em>So the result is the graph shown below
You have 90 and you have 15%
so you have to subtract 90 and 15%
90-15%=76.5
