If I would drive to work and back for a week I would approximately drive for 210 miles. If I were to drive around and go hang out with friends I would drive around 350 miles per week. If I go 400 miles a week and my whole gas tanks goes 250 miles per tank then it would cost around 37.00$ a week for gas. It would cost around 148 dollars a month going 350 miles a week. That means I would spend 1776 dollars a year spending 148 dollars a month.

I read the article about using cloth diapers instead of disposable diapers. It was very interesting to learn about this because I have a little sister that is two and it did seem like we were using a lot of diapers for her. I learned in this article that the average cost for diapers from birth to potty train is around 2,500$. But from cloth the average is about 480$. In a year people use enough diapers to fill up a football stadium 3 times in one year. And it takes many lifetimes for a diaper to decompose. It is fascinating that you can save so much money in a year just from changing to cloth diapers.

if i could get a car it would be a honda fit. it is small like me and i would not spend as much gas money as other peopl. it has a gas tank that holds 7 gallons and get 28mpg city and 35 mpg highway. if the gas prices were three dollars and thirty one cents to fill up my tank it would be 25.17$ to completely fill up the tank. and i could go 245 miles per tank.
