How much would you spend on gasoline each year if you drove 10,000 miles over the year and your vehicle achieves 15 miles per gallon with gasoline priced at $4.00 a gallon? Now substitute your vehicle for a hybrid-electric automobile that achieves 60 miles per gallon. Calculate the yearly cost for fuel with this vehicle.
Driving 10,000 miles at 15 miles per gallon would require 666.67 gallons of gasoline (10,000 divided by 15). At $4.00 per gallon, this would cost $2,666.68 per year.
Driving 10,000 miles at 60 miles per gallon would only require 166.67 gallons of gasoline (10,000 divided by 60). At $4.00 per gallon, this would only cost $666.68 per year with a hybrid-electric automobile.
