The current raw material cost for petroleum from the well is

The current raw material cost for petroleum from the well is dollar 40 per barrel Natural gas has been averaging sim dollar 3.00 per million Btu (from the well) The USA has been consuming about 7 billion barrels of oil per year. The entire world has been consuming about 37 billion barrels per year China and India\'s consumption of oil is growing about 10 percent per year Tax on gasoline in Idaho is 50 cents per gallon at the pump. Federal + State. A gallon of gas has about 125,000 Btu (130 MJ) of heat of combustion available There are 42 gallons in an international barrel of oil The current price of a gallon of gasoline in Idaho is about dollar 2.20 per gallon One million Btu of gasoline costs dollar. If the price of oil at the well is raised from the current dollar 40 per barrel to dollar 100 per barrel, the cost of a gallon of gasoline would be increased by cents (per gallon) For a car getting 25 miles per gallon, the fuel cost is cents per mile If you could purchase natural gas for your car at dollar 5 per million Btu, and the engine operated at the same efficiency as with gasoline, the fuel cost for driving would be cents per mile using natural gas. How many kWh does it take to drive a standard mid-size automobile one mile on the level? (Assume 30 miles per gallon for the equivalent regular car, an efficiency of 25 percent in using the gasoline, and 80 percent in using battery and electric motor.) kWh per mile Why does the standard (not plug-in type) hybrid vehicle get much better city gas mileage than its all-gasoline brother? (Toyota Camry and Ford Fusion examples, for instance). Give at least two reasons (choose 3 to be safe!):

Solution

14) it costs $ 3.00

16) 2 cents per mile
