## Problem Description and Formulation

The problem is an optimization problem with two variables: 'hours worked by Laura' and 'hours worked by Ringo'. The objective is to minimize the function 6.49 times the hours worked by Laura plus 9.41 times the hours worked by Ringo, subject to several constraints.

### Variables and Resources

- Variables: 
  - $x_0$: hours worked by Laura
  - $x_1$: hours worked by Ringo

- Resources/Attributes:
  - $r_0$: paperwork competence rating
  - $r_1$: organization score
  - $r_2$: productivity rating

### Constraints

1. Individual ratings for Laura and Ringo.
   - Laura's paperwork competence rating: $8x_0$
   - Laura's organization score: $11x_0$
   - Laura's productivity rating: $7x_0$
   - Ringo's paperwork competence rating: $4x_1$
   - Ringo's organization score: $7x_1$
   - Ringo's productivity rating: $2x_1$

2. Combined ratings constraints.
   - Paperwork competence rating: $8x_0 + 4x_1 \geq 36$
   - Organization score: $11x_0 + 7x_1 \geq 44$
   - Productivity rating: $7x_0 + 2x_1 \geq 28$

3. Upper bounds for combined ratings.
   - Paperwork competence rating: $8x_0 + 4x_1 \leq 60$
   - Organization score: $11x_0 + 7x_1 \leq 100$
   - Productivity rating: $7x_0 + 2x_1 \leq 54$

4. Additional constraint.
   - $10x_0 - 5x_1 \geq 0$

### Gurobi Code Formulation

```python
import gurobi

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

    # Define variables
    x0 = model.addVar(name="hours_worked_by_Laura", lb=0)  # Assuming hours cannot be negative
    x1 = model.addVar(name="hours_worked_by_Ringo", lb=0)  # Assuming hours cannot be negative

    # Objective function: Minimize 6.49*x0 + 9.41*x1
    model.setObjective(6.49 * x0 + 9.41 * x1, gurobi.GRB.MINIMIZE)

    # Constraints
    # Individual constraints (not actually needed as they are constants)
    # model.addConstr(8 * x0 <= 75)  # Laura's paperwork
    # model.addConstr(11 * x0 <= 100)  # Laura's organization
    # model.addConstr(7 * x0 <= 103)  # Laura's productivity
    # model.addConstr(4 * x1 <= 75)  # Ringo's paperwork
    # model.addConstr(7 * x1 <= 100)  # Ringo's organization
    # model.addConstr(2 * x1 <= 103)  # Ringo's productivity

    # Combined constraints
    model.addConstr(8 * x0 + 4 * x1 >= 36)  # Paperwork min
    model.addConstr(11 * x0 + 7 * x1 >= 44)  # Organization min
    model.addConstr(7 * x0 + 2 * x1 >= 28)  # Productivity min

    model.addConstr(8 * x0 + 4 * x1 <= 60)  # Paperwork max
    model.addConstr(11 * x0 + 7 * x1 <= 100)  # Organization max
    model.addConstr(7 * x0 + 2 * x1 <= 54)  # Productivity max

    model.addConstr(10 * x0 - 5 * x1 >= 0)  # Additional constraint

    # Solve the model
    model.optimize()

    # Print the solution
    if model.status == gurobi.GRB.OPTIMAL:
        print("Optimal Solution:")
        print(f"Hours worked by Laura: {x0.varValue}")
        print(f"Hours worked by Ringo: {x1.varValue}")
        print(f"Objective: {model.objVal}")
    else:
        print("No optimal solution found.")
