**Problem 4(a) (30 points):**

**Question:** Use a graphical approach to find the maximum and minimum of \( W = 2x + 5y \).

**Subject to:**

1. \( x + y \geq 4 \)
2. \( -x + y \leq 6 \)
3. \( x + 3y \leq 30 \)
4. \( x \leq 12 \)
5. \( x \geq 0 \)
6. \( y \geq 0 \)

**Instructions:** Graph the constraints to form a feasible region. Identify the vertices of this region, and calculate the value of \( W \) at each vertex to determine the maximum and minimum values.

---

Note: To fully solve this problem, plot each inequality on the Cartesian plane, find the intersection points that satisfy all conditions, and evaluate \( W = 2x + 5y \) at those points.
