Question 8

Given constraints: x 0, y 0, 2x + 2y 4, x + y 8Explain the steps for maximizing the objective function P = 3x + 4y.

Revolt · Accepted Answer

To maximize the objective function, first graph the system of linear inequalities defined by the constraints to identify the feasible region. Next, determine the vertices (corner points) of this region by finding the intersection points of the boundary lines. Then, evaluate the objective function, P = 3x + 4y, at each of these vertices. Finally, compare the results; the vertex that produces the largest value is the point that maximizes the function.
