Joe is using the function E= 1.89x + 2.89y to minimize his expenses when selling markers and erasers. He has the following
constraints.
2x + y > 10
x + 2y > 8
X>0
y >
What is the minimum value of E?
$28.90
$9.45
$15.12
$13.34

Step-by-step explanation:

Given

-- Objective function

Constraints:

Required

Minimum value of E

To do this, we apply graphical method

See attachment for plots of and

From the attached plot, the point that satisfy is:

So, we have:

This gives:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
