## Problem Description and Formulation

The problem requires maximizing the objective function: 

\[ 6 \times \text{corn cobs} + 1 \times \text{protein bars} + 8 \times \text{strips of bacon} + 4 \times \text{steaks} \]

subject to various constraints on the carbohydrate content from different food items.

## Constraints

1. Carbohydrate content from each item:
   - Corn cobs: 3 grams
   - Protein bars: 5 grams
   - Strips of bacon: 4 grams
   - Steaks: 6 grams

2. Minimum carbohydrate requirements from combinations of food items.
