Solution
Solution Steps
To solve this linear programming problem, we need to find the feasible region defined by the constraints and then evaluate the objective function \( P = 30x + 10y \) at each vertex of this region. The minimum and maximum values of \( P \) will occur at one of these vertices. We will use Python's scipy.optimize.linprog to find these values.
Step 1: Define the Objective Function and Constraints
We are given the objective function to optimize:
\[ P = 30x + 10y \]
The constraints for the system are:
\[
\begin{align_}
2x + 2y & \geq 4 \\
6x + 4y & \leq 36 \\
2x + y & \leq 10 \\
x, y & \geq 0
\end{align_}
\]
Step 2: Convert Inequalities for Linear Programming
To use linear programming, we convert the inequalities:
\[
\begin{align_}
2x + 2y & \geq 4 \quad \Rightarrow \quad -2x - 2y \leq -4 \\
6x + 4y & \leq 36 \\
2x + y & \leq 10
\end{align_}
\]
Step 3: Solve for Maximum and Minimum Values
Using the constraints, we find the feasible region and evaluate the objective function at the vertices of this region. The results are:
The minimum value of \( P \) is \(-20\) and occurs at the point \((0, 2)\).
The maximum value of \( P \) is \(150\) and occurs at the point \((5, 0)\).
Final Answer
The minimum value of \( P \) is \(\boxed{-20}\) and occurs at \(\boxed{(0, 2)}\).
The maximum value of \( P \) is \(\boxed{150}\) and occurs at \(\boxed{(5, 0)}\).
