## Step 1: Define the symbolic representation of the problem
The problem involves 7 variables: ['hours worked by Paul', 'hours worked by Ringo', 'hours worked by Dale', 'hours worked by Hank', 'hours worked by Bill', 'hours worked by Jean', 'hours worked by Peggy']. Let's denote them as $x_0, x_1, x_2, x_3, x_4, x_5, x_6$ respectively.

## Step 2: Formulate the objective function
The objective function to minimize is $6.63x_0 + 6.54x_1 + 2.03x_2 + 9.2x_3 + 8.24x_4 + 9.16x_5 + 7.76x_6$.

## Step 3: List the constraints
There are numerous constraints provided, including:
- Organization score constraints: $x_0, x_1, ..., x_6$ have upper bounds based on organization scores.
- Likelihood to quit index constraints: $x_0, x_1, ..., x_6$ have upper bounds based on likelihood to quit indices.
- Productivity rating constraints: $x_0, x_1, ..., x_6$ have upper bounds based on productivity ratings.
- Work quality rating constraints: $x_0, x_1, ..., x_6$ have upper bounds based on work quality ratings.
- Combined constraints, e.g., $3x_0 + 5x_1 + 10x_3 \geq 36$, $7x_1 + 2x_4 \geq 40$, etc.
