## Step 1: Define the symbolic representation of the variables
The variables are ['scissors', 'smoke detectors', 'hole punches', 'mechanical pencils'] which can be represented symbolically as ['x0', 'x1', 'x2', 'x3'].

## Step 2: Create a dictionary mapping symbolic variables to their natural language counterparts
The symbolic variables and their natural language counterparts are:
- x0: scissors
- x1: smoke detectors
- x2: hole punches
- x3: mechanical pencils

## Step 3: Formulate the objective function using symbolic variables
The objective function to maximize is $5.78x0 + 4.79x1 + 1.44x2 + 8.87x3$.

## 4: List all the constraints in symbolic form
Constraints:
1. $3x0 + 26x1 + 11x2 + 6x3 \leq 373$ (storage space)
2. $22x0 + 21x1 + 28x2 + 9x3 \leq 294$ (sustainability score)
3. $26x1 + 11x2 \geq 75$ (storage space for smoke detectors and hole punches)
4. $26x1 + 6x3 \geq 77$ (storage space for smoke detectors and mechanical pencils)
5. $3x0 + 26x1 + 6x3 \geq 93$ (storage space for scissors, smoke detectors, and mechanical pencils)
6. $21x1 + 28x2 \leq 105$ (sustainability score for smoke detectors and hole punches)
7. $28x2 + 9x3 \leq 122$ (sustainability score for hole punches and mechanical pencils)
8. $22x0 + 9x3 \leq 144$ (sustainability score for scissors and mechanical pencils)
9. $22x0 + 28x2 \leq 140$ (sustainability score for scissors and hole punches)
10. $22x0 + 28x2 + 9x3 \leq 93$ (sustainability score for scissors, hole punches, and mechanical pencils)
11. $22x0 + 21x1 + 28x2 + 9x3 \leq 93$ (sustainability score for all items)
12. $3x0 + 26x1 \leq 327$ (storage space for scissors and smoke detectors)
13. $3x0 + 6x3 \leq 157$ (storage space for scissors and mechanical pencils)
14. $3x0 + 11x2 \leq 251$ (storage space for scissors and hole punches)
15. $11x2 + 6x3 \leq 175$ (storage space for hole punches and mechanical pencils)
16. $3x0 + 26x1 + 6x3 \leq 184$ (storage space for scissors, smoke detectors, and mechanical pencils)
17. $3x0 + 26x1 + 11x2 + 6x3 \leq 184$ (storage space for all items)
18. $x0, x1, x2, x3 \geq 0$ and are integers.

## 5: Provide the symbolic representation of the problem

    model.addConstr(3*x0 + 26*x1 + 11*x2 + 6*x3 <= 184, name="storage_all")

    # Integrate all the constraints
    model.update()

    # Solve the model
    model.optimize()

    # Print the solution
    if model.status == gurobi.GRB.OPTIMAL:
