Answer: x > 38
In this case, x is a exterior angle of the triangle. The exterior angle of a triangle is the sum of the nonadjacent interior angles of the triangle.
Therefore:
x = 38 + 39
x = 77
77 > 38
x > 38
we have the following system of equations

we know that
The intersection of both graphs is the solution of the system of equations
using a graph tool
see the attached figure
the solution is the point 
therefore
<u>the answer is</u>
the solution of the system of equations is the point 
First $25,000: Commission = 1/100*25000 = $250
$25,001 to $95,000: Commission = 3/100*(95000-25000) = $2,100
Above $95,000: Commission = 5/100*(100000-95000) = $250
Total commission earned = 250+2100+250 = $2,600
