To maximize the objective function $P = 3x_1 + 6x_2 + 32x_3$ subject to the given constraints, we will first formulate this as a Linear Programming (LP) problem and then solve it using the Simplex Method or other methods. The constraints and non-negativity conditions are:

Objective Function:

$P = 3x_1 + 6x_2 + 32x_3$

Constraints:

1. $x_1 + 6x_2 + 24x_3 \leq 672$
2. $3x_1 + x_2 + 24x_3 \leq 336$
3. $x_1 + 3x_2 + 16x_3 \leq 168$
4. $2x_1 + 3x_2 + 32x_3 \leq 352$
5. $x_1, x_2, x_3 \geq 0$

Approach:

The problem can be solved using linear programming techniques. Let me solve it step by step:

1. Convert inequalities to equalities by introducing slack variables: For each inequality constraint, we introduce a slack variable to convert it into an equality.

2. Set up the simplex tableau: Using the constraints and objective function, the simplex method can then be applied to find the optimal values of $x_1$, $x_2$, and $x_3$.

However, since solving the linear programming problem manually involves iterative steps, I'll first compute the optimal solution for you.

I'll calculate the values now! scipy.optimize import linprog

Coefficients for the objective function (maximize P = 3x1 + 6x2 + 32x3)

c = [-3, -6, -32] # We negate the coefficients for maximization

Coefficients for the inequality constraints

A = [ [1, 6, 24], # x1 + 6x2 + 24x3 <= 672 [3, 1, 24], # 3x1 + x2 + 24x3 <= 336 [1, 3, 16], # x1 + 3x2 + 16x3 <= 168 [2, 3, 32], # 2x1 + 3x2 + 32x3 <= 352 ]

Right-hand side values for the constraints

b = [672, 336, 168, 352]

Bounds for x1, x2, x3 (x1, x2, x3 >= 0)

x0_bounds = (0, None) x1_bounds = (0, None) x2_bounds = (0, None)

Solve the linear programming problem using linprog

result = linprog(c, A_ub=A, b_ub=b, bounds=[x0_bounds, x1_bounds, x2_bounds], method='highs')

Extract the solution

result_x = result.x result_max_P = -result.fun # Negate to get the maximized P

result_x, result_max_PThe optimal solution to the linear programming problem is:

• $x_1 = 105$
• $x_2 = 21$
• $x_3 = 0$

The maximum value of $P$ is $P = 441$.
