## Step 1: Define the optimization problem
The goal is to maximize the objective function: $2.02 \times \text{cornichons} + 2.38 \times \text{fruit salads} + 1.8 \times \text{slices of pizza} + 4.35 \times \text{cherry pies} + 5.67 \times \text{blueberry pies}$.

## 2: List all variables and their coefficients in the objective function
- Cornichons: 2.02
- Fruit salads: 2.38
- Slices of pizza: 1.8
- Cherry pies: 4.35
- Blueberry pies: 5.67

23. $-7 \times \text{slices of pizza} + 2 \times \text{cherry pies} + 8 \times \text{blueberry pies} \geq 0$
24. $8 \times \text{cornichons} + 7 \times \text{fruit salads} \leq 241$

# Solve the model
