Let's start solving part (a), where we need to formulate the problem as a Linear Programming (LP) model.

### Problem:
Reddy Mikks produces two types of paint:
- Exterior paint
- Interior paint

It uses two raw materials, **M1** and **M2**, and we are given the following:
- **Exterior paint** requires:
  - 6 tons of M1
  - 1 ton of M2
  - Yields a profit of \$5,000 per ton
  
- **Interior paint** requires:
  - 4 tons of M1
  - 2 tons of M2
  - Yields a profit of \$4,000 per ton

The **availability** of the raw materials is:
- M1: 24 tons per day
- M2: 6 tons per day

### Goal:
Maximize the total daily profit by determining the optimal product mix of interior and exterior paints.

### Decision Variables:
Let:
- $ x_1 $ = tons of exterior paint produced per day
- $ x_2 $ = tons of interior paint produced per day

### Objective Function:
Maximize the profit:
\[
Z = 5000x_1 + 4000x_2
\]

### Constraints:
We need to ensure the use of raw materials does not exceed the daily availability:

- **M1 constraint (for both types of paint)**:
  \[
  6x_1 + 4x_2 \leq 24
  \]
  (since 6 tons of M1 is used for each ton of exterior paint and 4 tons of M1 for each ton of interior paint)

- **M2 constraint**:
  \[
  x_1 + 2x_2 \leq 6
  \]
  (since 1 ton of M2 is used for each ton of exterior paint and 2 tons for each ton of interior paint)

- **Non-negativity constraints**:
  \[
  x_1 \geq 0, \quad x_2 \geq 0
  \]

### Linear Programming Model:
\[
\text{Maximize } Z = 5000x_1 + 4000x_2
\]
Subject to:
\[
6x_1 + 4x_2 \leq 24
\]
\[
x_1 + 2x_2 \leq 6
\]
\[
x_1 \geq 0, \quad x_2 \geq 0
\]

This formulation represents the problem mathematically.
