Given -The average gallon of gas contains about 5 lbs. of carbon.
-One five-pound bag of charcoal briquettes contains approximately 100 briquettes.
-5 lbs. of carbon/100 briquettes = 0.05 lbs. carbon per briquette
* Sample Problems
1. If you drive or ride in a vehicle that averages 25 mpg, how many briquettes per mile would you be emitting?
2. If each briquette contains 0.05 lbs. of carbon, how many lbs. of carbon are emitted each mile?
