Hi, my name is Sam and I'm here to ask you to sign our petition. the problem that we are trying to stop is car exhaust. we came up with and idea that we think can help this world to cut down the amount of air pollution, we were calling because we would like an opinion about our idea. His answer yes or no the idea is a muffler that you put on the end of an exhaustion pipe that will cut down all the carbon dioxide and pollution that comes out, and turns all that bad air into good fresh air. a car produces 27.7843835616 pounds of Co2 per day. there are 6,433,000 cars in L.A. so if you multiply those two numbers, the result is catastrophic. but i'll help you so you don't have to do the math. That's 178,736,939.452 pounds produced per day. now, let's find how much is produced a year, one car creates 4.6 metric tons a year. now, that number in pounds. that's 10141.3 pounds per year. now add all the cars in L.A. and that number is... ready? 65,238,982,900 of carbon dioxide is produced in Los Angeles from cars per year. we really hope that you sign our petition to help revert tis crisis. thank you for your time
