Total pens and pencils is 22
So,
----------------(1)
And he bought all utensils for $11.95. and each pen for 75 cents and pencils for 40 cents.
------------(2)
solve equation 1 and equation 2 for x and y.
From equation 1.

----------------(3)
put y value in equation 2.

Answer:
D)
, 
Step-by-step explanation:
The blue boundary line has a y-intercept of 2 and a slope of 2.
It has equation : 
Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is

The blue boundary line passes through the origin and has slope
.
Its equation is 
Since the boundary line is not solid and the right half-plane is shaded, its inequality is 
The correct choice is D.
The answer would be B because a line is a parallel as long as the mx remains the same
Hope this helped.
Just do 7/4 and cross multiply with 1/2
