## Step 1: Define the variables and their corresponding natural language objects
Let's denote the variables as follows:
- $x_1$ : hours worked by Paul
- $x_2$ : hours worked by Hank
- $x_3$ : hours worked by Bobby
- $x_4$ : hours worked by Mary
- $x_5$ : hours worked by Ringo
- $x_6$ : hours worked by John

## Step 2: Define the objective function in terms of symbolic variables
The objective function to minimize is: $9x_1 + 4x_2 + 3x_3 + x_4 + 7x_5 + 8x_6$

## Step 3: List the constraints
Constraints from individual ratings:
- $8x_1 \leq 145$ (paperwork competence rating for Paul)
- $5x_1 \leq 167$ (productivity rating for Paul)
- $8x_2 \leq 145$ (paperwork competence rating for Hank)
- $3x_2 \leq 167$ (productivity rating for Hank)
- $9x_3 \leq 145$ (paperwork competence rating for Bobby)
- $4x_3 \leq 167$ (productivity rating for Bobby)
- $5x_4 \leq 145$ (paperwork competence rating for Mary)
- $9x_4 \leq 167$ (productivity rating for Mary)
- $4x_5 \leq 145$ (paperwork competence rating for Ringo)
- $3x_5 \leq 167$ (productivity rating for Ringo)
- $10x_6 \leq 145$ (paperwork competence rating for John)
- $11x_6 \leq 167$ (productivity rating for John)
