## Step 1: Define the optimization problem and identify the variables, objective function, and constraints.
The optimization problem involves minimizing an objective function subject to various constraints. The variables are 'hot dogs', 'blueberry pies', 'milkshakes', and 'bowls of cereal'. The objective function to minimize is $8 \times \text{hot dogs} + 7 \times \text{blueberry pies} + 8 \times \text{milkshakes} + 3 \times \text{bowls of cereal}$.

## 2: List all the constraints based on the problem description.
The constraints are as follows:
1. $\text{hot dogs} \times 22 + \text{blueberry pies} \times 17 + \text{milkshakes} \times 23 + \text{bowls of cereal} \times 11 \leq 435$ (protein constraint)
2. $\text{hot dogs} \times 4 + \text{blueberry pies} \times 19 + \text{milkshakes} \times 14 + \text{bowls of cereal} \times 13 \leq 315$ (calcium constraint)
3. $\text{blueberry pies} \times 17 + \text{milkshakes} \times 23 \geq 73$ (minimum protein from blueberry pies and milkshakes)
4. $\text{hot dogs} \times 22 + \text{milkshakes} \times 23 \geq 107$ (minimum protein from hot dogs and milkshakes)
5. $\text{hot dogs} \times 22 + \text{blueberry pies} \times 17 + \text{milkshakes} \times 23 + \text{bowls of cereal} \times 11 \geq 107$ (minimum total protein)
6. $\text{hot dogs} \times 4 + \text{milkshakes} \times 14 \geq 45$ (minimum calcium from hot dogs and milkshakes)
7. $\text{milkshakes} \times 14 + \text{bowls of cereal} \times 13 \geq 28$ (minimum calcium from milkshakes and bowls of cereal)
8. $\text{blueberry pies} \times 19 + \text{milkshakes} \times 14 \geq 27$ (minimum calcium from blueberry pies and milkshakes)
9. $\text{hot dogs} \times 4 + \text{blueberry pies} \times 19 \geq 67$ (minimum calcium from hot dogs and blueberry pies)
10. $\text{hot dogs} \times 4 + \text{bowls of cereal} \times 13 \geq 43$ (minimum calcium from hot dogs and bowls of cereal)
11. $\text{hot dogs} \times 4 + \text{blueberry pies} \times 19 + \text{milkshakes} \times 14 + \text{bowls of cereal} \times 13 \geq 43$ (minimum total calcium)
12. $-8 \times \text{hot dogs} + 8 \times \text{bowls of cereal} \geq 0$ (relationship between hot dogs and bowls of cereal)
13. $\text{blueberry pies} \times 1 - 10 \times \text{milkshakes} \geq 0$ (relationship between blueberry pies and milkshakes)
14. $\text{hot dogs} \times 22 + \text{bowls of cereal} \times 11 \leq 143$ (maximum protein from hot dogs and bowls of cereal)
15. $\text{hot dogs} \times 22 + \text{milkshakes} \times 23 \leq 247$ (maximum protein from hot dogs and milkshakes)
16. $\text{hot dogs} \times 22 + \text{blueberry pies} \times 17 + \text{bowls of cereal} \times 11 \leq 222$ (maximum protein from hot dogs, blueberry pies, and bowls of cereal)
17. $\text{hot dogs} \times 22 + \text{milkshakes} \times 23 + \text{bowls of cereal} \times 11 \leq 138$ (maximum protein from hot dogs, milkshakes, and bowls of cereal)
18. $\text{hot dogs} \times 22 + \text{blueberry pies} \times 17 + \text{milkshakes} \times 23 \leq 166$ (maximum protein from hot dogs, blueberry pies, and milkshakes)
19. $\text{milkshakes} \times 14 + \text{bowls of cereal} \times 13 \leq 187$ (maximum calcium from milkshakes and bowls of cereal)

## 3: Define the variables and their types.
- $\text{hot dogs}$: integer
- $\text{blueberry pies}$: continuous
- $\text{milkshakes}$: continuous
- $\text{bowls of cereal}$: integer

## 4: Implement the optimization problem using Gurobi.

    model.addConstr(-8 * hot_dogs + 8 * bowls_of_cereal >= 0)
    model.addConstr(blueberry_pies - 10 * milkshakes >= 0)
    model.addConstr(22 * hot_dogs + 11 * bowls_of_cereal <= 143)

    model.addConstr(14 * milkshakes + 13 * bowls_of_cereal <= 187)

    # Solve the model
    model.optimize()

    # Print the solution
    if model.status == gurobi.GRB.OPTIMAL:
        print("Objective: ", model.objVal)
        print("Hot dogs: ", hot_dogs.varValue)
