Given:
The graph of a system of inequalities.
To find:
The ordered pair which is a solution to the graphed inequality.
Solution:
The boundary lines are:


From the given graph it is clear that only point (3,1) lies in the shaded region.
Points (2,-1) and (4,0) lie on the boundary line
but the boundary line is dotted. It means the points on the line are not in the solution set.
point (0,-1) does not belong to the shaded region.
Therefore, the correct option is A.

100 $;
<span> discount of 20% => 80$;
</span> discount of <span>12%</span>% => 80 - 80*(12/100) = 71.4 $;
100 - (x/100)*100 = 71.4 => x = 29.6 => a single discount of 29.6%;
