How much money has Petro Refinery LLC been making per week under its current production policy of processing 700,000 barrels of light and 120,000 barrels of heavy crude after subtracting the labor costs, the variable overhead costs, and the weekly fixed overhead costs? 2. The demand forecast for next week indicates that Petro Refinery LLC need to process 650,000 barrels of light and 350,000 barrels of heavy crude. Determine the light crude-heavy crude processing combination in barrels for next week that will maximize the profit using: A. The traditional method B. The bottleneck method 3. Which method in Question 2 results in higher profit and why? 4. Suppose blending is available for an extra 250 hours per week. How would that affect your findings in Question 2? 5. Suppose the price of heavy crude increases by $3/barrel (with light remaining the same). How would that affect your findings in Question 2?
