**Summary of the Problem:**

1. **Context:** 
   - The company "VAO" produces three products (A, B, and C) from two raw materials (MP1 and MP2). 
   - It mentions the materials required to produce a unit of each product:
     - **A:** Requires 3 kg of MP1 and 4 kg of MP2.
     - **B:** Requires 5 kg of MP1 and 4 kg of MP2.
     - **C:** Requires 2 kg of MP1 and 1 kg of MP2.
   - There is a demand limit:
     - Maximum 80 units of A.
     - Maximum 60 units of B.
     - Maximum 40 units of C.
   - There are resource constraints:
     - 400 kg of MP1 available.
     - 300 kg of MP2 available.

2. **Objective:**
   - Maximize the company's profit.
   - The profit for each product is provided:
     - **A:** $150.
     - **B:** $100.
     - **C:** $90.

3. **Required Tasks:**
   - Formulate a linear programming (LP) model.
   - Define decision variables, an objective function, and constraints based on the material usage, demand, and availability.

**Key Steps:**

1. **Decision Variables:**
   - Let $ x_A $, $ x_B $, and $ x_C $ be the number of units produced for products A, B, and C, respectively.

2. **Objective Function:**
   - Maximize profit:
   \[
   Z = 150x_A + 100x_B + 90x_C
   \]

3. **Constraints:**
   - Material constraints:
     - MP1: $ 3x_A + 5x_B + 2x_C \leq 400 $
     - MP2: $ 4x_A + 4x_B + x_C \leq 300 $
   - Demand constraints:
     - $ x_A \leq 80 $
     - $ x_B \leq 60 $
     - $ x_C \leq 40 $
   - Non-negativity: $ x_A, x_B, x_C \geq 0 $.
