Max Z = 40x1 + 30x2 + 30x3 s.t 6x1 + 2x2 + 5x3 ≤ 200 4x1 + 5x2 + 3x3 ≤ 150 x1 , x2 , x3 ≥ 0

You are dealing with a **linear programming** problem, where the goal is to maximize the objective function \( Z = 40x_1 + 30x_2 + 30x_3 \), subject to the constraints:

1. \( 6x_1 + 2x_2 + 5x_3 \leq 200 \)
2. \( 4x_1 + 5x_2 + 3x_3 \leq 150 \)
3. \( x_1, x_2, x_3 \geq 0 \)

To solve this, we typically use the **Simplex Method** or software like Excel, Python, or other optimization tools. Here's the step-by-step process conceptually:

### Step 1: Write the Standard Form
Convert the inequalities into equalities by introducing **slack variables**. The constraints become:

\[
6x_1 + 2x_2 + 5x_3 + s_1 = 200
\]
\[
4x_1 + 5x_2 + 3x_3 + s_2 = 150
\]
Where \( s_1 \) and \( s_2 \) are slack variables representing unused resources and \( s_1, s_2 \geq 0 \).

The new objective function to maximize is still \( Z = 40x_1 + 30x_2 + 30x_3 \).

### Step 2: Initial Simplex Tableau
Set up the initial tableau for the simplex method, including coefficients of variables \( x_1, x_2, x_3, s_1, s_2 \) from both constraints and the objective function.

### Step 3: Iterations of Simplex Method
By applying pivot operations, we can iteratively find the values of \( x_1, x_2, x_3 \) that maximize \( Z \).

Would you like a detailed solution using the Simplex method, or would you prefer I solve it using Python for a quicker answer?
