Solve the following lp problem graphically by enumerating the corner points. hint: find all the corner points and plug those values in the objective function then take the largest value - to find the corner points, you need to find the intersection of two lines solving simultaneously. max: 3x1 + 4x2 subject to: x1 ≤ 12 x2≤ 10 4x1 + 6x2 ≤ 72 x1, x2 ≥ 0
