🔍 Key Concepts
• Use the API Gravity 60°F = 30.4 row in the left block of the table.
• Pick the correct column: you have gallons and want weight, so you need pounds per U.S. gallon at 60°F, not gallons per pound.
• Convert total pounds of fuel to long tons (1 long ton = 2,240 lb) after you multiply.
💭 Think About
• From the table, what is the number of pounds per gallon that corresponds exactly to API 30.4?
• Once you multiply pounds/gallon by 25,000 gallons, how many total pounds do you get, and what happens when you divide that by 2,240?
• After converting to long tons, which answer choice is closest to your calculated value?
✅ Before You Answer
• Confirm you used the 30.4 API row, not 30.0 or 31.0.
• Verify you selected pounds per U.S. gallon (left numeric column for that row), not U.S. gallons per pound.
• Double‑check the final step uses 1 long ton = 2,240 lb, not 2,000 lb (short ton).
