## Step 1: Define the symbolic representation of the variables
The variables are 'steaks', 'pickles', 'strawberries', 'bowls of pasta' which can be represented symbolically as 'x1', 'x2', 'x3', 'x4' respectively.

## Step 2: Convert the objective function into a symbolic representation
The objective function to minimize is $7.17 \times \text{steaks} + 5.44 \times \text{pickles} + 5.24 \times \text{strawberries} + 3.15 \times \text{bowls of pasta}$. In symbolic terms, this becomes $7.17x_1 + 5.44x_2 + 5.24x_3 + 3.15x_4$.

## 3: List the constraints in symbolic notation
1. $\text{steaks} \geq 0$, $\text{pickles} \geq 0$, $\text{strawberries} \geq 0$, $\text{bowls of pasta} \geq 0$ (non-negativity constraints, but not explicitly needed as Gurobi assumes non-negativity by default for continuous variables).
2. $2\text{steaks} + 13\text{pickles} + 2\text{strawberries} + 2\text{bowls of pasta} \leq 234$ (total cost constraint).
3. $2\text{steaks} + 2\text{strawberries} \geq 39$ (steaks and strawberries cost constraint).
4. $2\text{steaks} + 2\text{bowls of pasta} \geq 46$ (steaks and bowls of pasta cost constraint).
5. $2\text{steaks} + 13\text{pickles} \geq 40$ (steaks and pickles cost constraint).
6. $2\text{steaks} + 13\text{pickles} + 2\text{strawberries} + 2\text{bowls of pasta} \geq 40$ (total cost constraint for all items).
7. $3\text{steaks} - 10\text{pickles} \geq 0$ (steaks and pickles relationship constraint).
8. $2\text{steaks} + 13\text{pickles} + 2\text{bowls of pasta} \leq 128$ (steaks, pickles, and bowls of pasta cost constraint).

## 4: Write down the symbolic representation of the problem
```json
{
    'sym_variables': [('x1', 'steaks'), ('x2', 'pickles'), ('x3', 'strawberries'), ('x4', 'bowls of pasta')],
    'objective_function': '7.17*x1 + 5.44*x2 + 5.24*x3 + 3.15*x4',
    'constraints': [
        '2*x1 + 2*x3 >= 39',
        '2*x1 + 2*x4 >= 46',
        '2*x1 + 13*x2 >= 40',
        '2*x1 + 13*x2 + 2*x3 + 2*x4 >= 40',
        '3*x1 - 10*x2 >= 0',
        '2*x1 + 13*x2 + 2*x4 <= 128',
        '2*x1 + 13*x2 + 2*x3 + 2*x4 <= 234'
    ]
}
```

## 5: Implement the optimization problem using Gurobi
```python
import gurobi

def solve_optimization_problem():
    # Create a new Gurobi model
    model = gurobi.Model()

    # Define the variables
    x1 = model.addVar(name="steaks", lb=0)
    x2 = model.addVar(name="pickles", lb=0)
    x3 = model.addVar(name="strawberries", lb=0)
    x4 = model.addVar(name="bowls of pasta", lb=0)

    # Define the objective function
    model.setObjective(7.17 * x1 + 5.44 * x2 + 5.24 * x3 + 3.15 * x4, gurobi.GRB.MINIMIZE)

    # Add constraints
    model.addConstr(2 * x1 + 2 * x3 >= 39)
    model.addConstr(2 * x1 + 2 * x4 >= 46)
    model.addConstr(2 * x1 + 13 * x2 >= 40)
    model.addConstr(2 * x1 + 13 * x2 + 2 * x3 + 2 * x4 >= 40)
    model.addConstr(3 * x1 - 10 * x2 >= 0)
    model.addConstr(2 * x1 + 13 * x2 + 2 * x4 <= 128)
    model.addConstr(2 * x1 + 13 * x2 + 2 * x3 + 2 * x4 <= 234)

    # Optimize the model
    model.optimize()

    # Print the solution
    if model.status == gurobi.GRB.OPTIMAL:
        print("Optimal solution found.")
        print(f"Steaks: {x1.varValue}")
        print(f"Pickles: {x2.varValue}")
        print(f"Strawberries: {x3.varValue}")
        print(f"Bowls of pasta: {x4.varValue}")
        print(f"Objective: {model.objVal}")
    else:
        print("No optimal solution found.")

solve_optimization_problem()
```
