To solve the problem presented in the image using Linear Programming (LP), let’s break it down step-by-step. We need to help Axis maximize his pleasure by allocating his study and play time, subject to some constraints.

Step 1: Define Variables

Let:

• $x$ represent the number of hours Axis spends studying.
• $y$ represent the number of hours Axis spends playing.

Step 2: Objective Function

The problem says that play is twice as enjoyable as studying, so we can define the objective function to maximize his total pleasure. Since play is twice as enjoyable as study, the total pleasure function will be: $P = x + 2y$ Where:

• $x$ is the study time.
• $y$ is the play time.

We want to maximize $P$.

Step 3: Constraints

The problem provides several constraints:

1. Axis has a total of 10 hours to allocate between study and play: $x + y \leq 10$
2. He wants to study at least as much as he plays, so: $x \geq y$
3. Axis can’t play more than 4 hours a day: $y \leq 4$
4. Both $x$ and $y$ must be non-negative: $x \geq 0, \quad y \geq 0$

Step 4: Formulate the Linear Program

We are now ready to formulate the Linear Program: $\text{Maximize} \quad P = x + 2y$ subject to: $x + y \leq 10$ $x \geq y$ $y \leq 4$ $x \geq 0, \quad y \geq 0$

Step 5: Graphing and Solving the Linear Program

To solve this LP problem, we can graph the constraints and find the feasible region. Then, we evaluate the objective function at the corner points of the feasible region.

Feasible Region:

• The inequality $x + y \leq 10$ is a line with slope -1. It will cut off the area to the left and below the line.
• The inequality $x \geq y$ means we are above or on the line $x = y$, which is a 45-degree diagonal line.
• The inequality $y \leq 4$ represents a horizontal line at $y = 4$.

We would graph these lines and find the intersection points to evaluate the objective function.

Step 6: Evaluate Objective Function at Corner Points

After graphing the constraints, find the corner points of the feasible region. Then, plug those points into the objective function $P = x + 2y$ to determine the maximum value.

Would you like me to calculate the intersection points and evaluate the objective function for you?
