The question asks about optimizing production to maximize profit, and this can be framed as a linear programming problem. Let's break down the setup.

Problem Summary:

• T50 DVD Player:

  • Uses 4 ounces of plastic
  • Uses 4 ounces of metal
  • Profit: $10 per unit
  • Max units: 20 units per week

• G150 DVD Player:

  • Uses 2 ounces of plastic
  • Uses 8 ounces of metal
  • Profit: $18 per unit

• Available materials:

  • 164 ounces of plastic
  • 464 ounces of metal

Goal:

Maximize profit by determining how many units of T50 and G150 should be produced, subject to material and production constraints.

Variables:

• Let $x$ = number of T50 units
• Let $y$ = number of G150 units

Constraints:

1. Plastic Constraint:
   $4x + 2y \leq 164$ (Total plastic used)

2. Metal Constraint:
   $4x + 8y \leq 464$ (Total metal used)

3. Production Limit for T50:
   $x \leq 20$

4. Non-negativity:
   $x \geq 0$, $y \geq 0$

Objective Function:

Maximize profit:
$\text{Profit} = 10x + 18y$

Solution Approach:

We will solve this using linear programming to find the values of $x$ and $y$ that maximize the profit while satisfying the constraints.
