**Solve the given linear programming problem using the table method.**

3) Maximize \( P = 6x_1 + 7x_2 \)

   Subject to:
   - \( 2x_1 + 3x_2 \leq 12 \)
   - \( 2x_1 + x_2 \leq 8 \)
   - \( x_1, x_2 \geq 0 \)

   Options:
   - A) \( \text{Max } P = 32 \text{ at } x_1 = 3, x_2 = 2 \)
   - B) \( \text{Max } P = 55 \text{ at } x_1 = 4, x_2 = 4 \)
   - C) \( \text{Max } P = 32 \text{ at } x_1 = 2, x_2 = 3 \)
   - D) \( \text{Max } P = 24 \text{ at } x_1 = 4, x_2 = 0 \)

3) _______

**Graph the system of inequalities.**

4)

   Inequalities:
   - \( x_1 + x_2 \leq 12 \)
   - \( 2x_1 + x_2 \leq 20 \)
   - \( x_1, x_2 \geq 0 \)

   **Graphs:**

   **A) Explanation:**
   - The graph shows a coordinate plane with \( x_1 \) on the horizontal axis and \( x_2 \) on the vertical axis.
   - The graph has a shaded area that represents the feasible region defined by the inequalities.
   - The lines for \( x_1 + x_2 = 12 \), \( 2x_1 + x_2 = 20 \), and the axes \( x_1 = 0 \), \( x_2 = 0 \) are clearly marked.
   - Key points, such as intersections on the feasible region, are labeled.

   **B) Description:**
   - Similar to graph A, this graph also represents the same inequalities in a coordinate plane.
   - The feasible region is slightly different, as shown by the altered intersection points and shaded area.
   - The constraints are depicted by straight lines
