ExxonMobil is evaluating the costs of expanding an oil refinery. The fixed expansion costs are $200,000,000, and the variable costs are $20 per barrel refined. ExxonMobil expects to refine 50,000,000 barrels in the first year. Additionally, environmental compliance costs are projected to be $30,000,000.

Requirements:

• Calculate the total expansion and environmental compliance costs.
• Determine the cost per barrel refined.
• Analyze the impact of refining an additional 10,000,000 barrels on total and per-barrel costs.
• Discuss the significance of managing environmental compliance costs.
• Recommend strategies for cost control in refinery operations.
