## Step 1: Define the symbolic representation of the problem
The symbolic representation of the problem consists of pairs of variables in symbolic notation and their corresponding natural language objects, the objective function rendered as an algebraic term, and the list of semi-algebraic constraints.

## Step 2: List the variables and their corresponding symbolic notation
Let's denote the variables as follows:
- Wooden pencils: $x_0$
- Rubber bands: $x_1$
- Smoke detectors: $x_2$
- Scissors: $x_3$
- Packs of paper: $x_4$
- Blue highlighters: $x_5$
- Hole punches: $x_6$

## Step 3: Formulate the objective function
The objective function to maximize is: $8x_0 + 2x_1 + 7x_2 + 5x_3 + 9x_4 + 7x_5 + 1x_6$

## Step 4: List the constraints
Constraints based on sustainability score:
- $x_0 + 14x_1 + 4x_2 + 5x_3 + 10x_4 + x_5 + 3x_6 \leq 226$
- $9x_0 + 10x_1 + x_2 + 12x_3 + 3x_4 + 9x_5 + 12x_6 \leq 467$

## Step 5: Define the symbolic representation in JSON format
```json
{
    'sym_variables': [
        ('x0', 'wooden pencils'),
        ('x1', 'rubber bands'),
        ('x2', 'smoke detectors'),
        ('x3', 'scissors'),
        ('x4', 'packs of paper'),
        ('x5', 'blue highlighters'),
        ('x6', 'hole punches')
    ],
    'objective_function': '8*x0 + 2*x1 + 7*x2 + 5*x3 + 9*x4 + 7*x5 + 1*x6',
    'constraints': [
        'x0 + 14*x1 + 4*x2 + 5*x3 + 10*x4 + x5 + 3*x6 <= 226',
        '9*x0 + 10*x1 + x2 + 12*x3 + 3*x4 + 9*x5 + 12*x6 <= 467',
        # Add all other constraints here...
        'x0 + 14*x1 + x5 + 3*x6 >= 18',
        '4*x2 + 5*x3 + x5 + 3*x6 >= 18',
        'x0 + 14*x1 + x5 >= 18',
        'x0 + 14*x1 + 4*x2 >= 18',
        '4*x2 + 5*x3 + x5 + 3*x6 >= 28',
        '12*x3 + 9*x5 >= 24',
        'x0, x1, x2, x3, x4, x5, x6 >= 0',
        'x0, x1, x2, x3, x4, x5, x6 == int(x0), int(x1), int(x2), int(x3), int(x4), int(x5), int(x6)'
    ]
}
```

## Step 6: Implement the optimization problem using Gurobi
```python

def solve_optimization_problem():
    model = gurobi.Model()

    # Define variables

    x3 = model.addVar(name="scissors", vtype=gurobi.GRB.INTEGER)
    x4 = model.addVar(name="packs_of_paper", vtype=gurobi.GRB.INTEGER)
    x5 = model.addVar(name="blue_highlighters", vtype=gurobi.GRB.INTEGER)
    x6 = model.addVar(name="hole_punches", vtype=gurobi.GRB.INTEGER)

    # Objective function
    model.setObjective(8*x0 + 2*x1 + 7*x2 + 5*x3 + 9*x4 + 7*x5 + x6, gurobi.GRB.MAXIMIZE)

    # Constraints
    model.addConstr(x0 + 14*x1 + 4*x2 + 5*x3 + 10*x4 + x5 + 3*x6 <= 226)
    model.addConstr(9*x0 + 10*x1 + x2 + 12*x3 + 3*x4 + 9*x5 + 12*x6 <= 467)

    # Add other constraints...

    model.addConstr(x0 + 14*x1 + x5 + 3*x6 >= 18)
    model.addConstr(4*x2 + 5*x3 + x5 + 3*x6 >= 18)
    model.addConstr(x0 >= 0)
    model.addConstr(x1 >= 0)
    model.addConstr(x2 >= 0)
    model.addConstr(x3 >= 0)
    model.addConstr(x4 >= 0)
    model.addConstr(x5 >= 0)
    model.addConstr(x6 >= 0)

    # Solve the model
    model.optimize()

    # Print the solution
    if model.status == gurobi.GRB.OPTIMAL:
        print("Objective: ", model.objVal)
        print("Wooden pencils: ", x0.varValue)
        print("Rubber bands: ", x1.varValue)
        print("Smoke detectors: ", x2.varValue)
        print("Scissors: ", x3.varValue)
        print("Packs of paper: ", x4.varValue)
        print("Blue highlighters: ", x5.varValue)
        print("Hole punches: ", x6.varValue)
    else:
        print("No solution found")

solve_optimization_problem()
```
