For this case, we first look for the number of blonde girls.
We have then:
We are now looking for the percentage of the class with blonde hair.
For this, we make the following rule of three:
30 --------------> 100%
4.25 -----------> x
From here, we clear the value of x.
We have then:
Answer:
14.2% of the class are blonds
Given inequalities are
and
Now we will graph both inequalities to get the common region which represents solution.
<u>Work for </u>
first we graph the line x+y=4 then shade the graph for inequality symbol 
we can plug any random number for x and find y-value to get points
lets plug x=0 then we get:
x+y=4
0+y=4
y=4
so the point is (0,4)
Similarly we can find more point like (4,0).
Now graph both points and join both points by straight line.
Now we find direction of shading.
pick any test point which is not on that line x+y=4 say (0,0)
and plug it into orinal inequality
which is true.
True means shade in direction of test point. Otherwise we shade in opposite direction.
We will repeat same process for other inequality to graph that.
Hence final graph for the answer will be as shown in attached image.
Triangular region ABC is final answer.
