The problem provided asks to modify the Low Knock Oil Company blending problem from Section 8.6 to account for a more realistic yield of gasoline from crude oil. In the original problem, it was assumed that one barrel of crude would produce one barrel of gasoline. However, the actual gasoline yield is only about 0.46 barrels from each barrel of crude oil, with the rest going to other products like diesel, jet fuel, home fuel oil, etc. The problem asks you to incorporate this information into the linear programming (LP) model for the company.

Here’s an outline to approach this:

### Step 1: Define Variables
- Let \( x_1, x_2, \dots \) represent the quantity of crude oil used from different sources (types of crude oil, for example).
- The yield of gasoline from each source is now modified to account for the 46% gasoline yield. For example, if \( x_1 \) represents the crude used, the yield of gasoline would now be \( 0.46x_1 \).

### Step 2: Modify the Objective Function
In the original LP model, the objective function is likely to maximize profit based on the quantities of crude oil and gasoline. The objective function now needs to reflect that only 46% of crude oil results in gasoline. If profit depends on the amount of gasoline produced, the objective function will need to include this 0.46 multiplier.

### Step 3: Modify the Constraints
The constraints of the original LP problem would likely include limits on crude oil availability and the demand for gasoline. These will now be adjusted to reflect the reduced gasoline yield:
- Availability constraints will stay the same for crude oil, but the gasoline production constraint will now only allow 46% of the crude oil used to count towards gasoline production.
- If the other products like diesel, jet fuel, etc., have their own demands, they should also be included in the new constraints.

### Step 4: Set Up the LP Problem in Software
To solve this, you can use software like **Excel Solver**, **MATLAB**, **Python** (using libraries such as PuLP), or other LP solvers. You'll need to input the objective function and constraints into the software.

Would you like a step-by-step guide to setting up this LP problem in Python or Excel? Let me know if you would like more detailed equations or further clarifications.

Here are 5 questions related to the problem:

1. What types of crude oil are considered in the original problem, and how do they affect the yield?
2. How does the production of other products (diesel, jet fuel, etc.) impact the overall blending strategy?
3. What constraints or limitations exist on the availability of crude oil or gasoline demand in the original LP problem?
4. How does reducing the gasoline yield to 46% change the profit-maximization strategy for the company?
5. Are there specific software packages or tools you're more comfortable using for LP problems?

**Tip:** When solving LP problems in software like Excel or Python, it's useful to first write out the objective function and constraints clearly on paper before implementing them in the program.

In the Low Knock Oil Company blending problem, account for the actual gasoline yield, where only 46% of crude turns into gasoline. Modify the linear programming model accordingly and solve the problem using any software.

Modify the Low Knock Oil Company linear programming model to reflect the actual gasoline yield from crude oil, where only 46% of the crude turns into gasoline.
