One gallon of gasoline burned in an automobile’s engine produces on the average 9.5 kg of carbon dioxide, which is a greenhouse gas, that is, it promotes the warming of Earth’s atmosphere. Calculate the annual production of carbon dioxide in kilograms if there are 40 million cars in the United States, and each car covers a distance of 5000 mi at a consumption rate of 20 mi per gallon.

A gasoline station in Manila, Philippines, charges 38.46 pesos per liter of unleaded gasoline at a time when one US. dollar (USD) buys 47.15 pesos (PHP). The car you are driving has a gas tank with a capacity of 14 U.S. gallons and gets 24 miles per gallon. (a) What is the cost of unleaded gasoline in Manila in USD per gallon? (b) How much would a tankful of unleaded gasoline for your car cost in USD? (c) Suppose that you have only PHP 1255 (a day's wage for an elementary school teacher) and the car's tank is almost empty. How many miles can you expect to drive if you spend all your money on gasoline?
