Back to the car

As gas prices decrease so does the amount of money I have to put in my car. since the lowest gas price is 1.64 i would have to pay 19.516 per tank of gas and it 48 mile to the gallon.

One thing i had learned while reading this a is about the gas prices. the thing i learned about them were 60% of gas consumtion is associated with going to work. Novak says this will bring a downpressure on oil prices. Plus the more employment rises your going to get a downward towards motor fuel. this is what i learned while reading the article.

polynomials

once i had watched the video i learned that you can't add 8x spuered to 8 x cubed so this is now clearer to me to solve more polynomial problems.

2 articles read

the article I read was 30 days/ways to save: hybrid v.s. fuel efficietcy cars. the reason i chose this is because my parents are looking for a great gas mileage car. I learned that in a year with the toyota prius will save us $565 on gas. another artical i read was 30 days/ways to save: slash your grocery bill. this relates to my parents because they can save 400-500 dallors for just 10 dallors a month.

Assignment #4

in a week a drive a few hundreded miles a week but with a 45 mile to the gallon car it'll be easy. The total amount of miles per week is about 345 counting family. Since i have a 45mpg rating you divide 345 by 45 and get 7.66666 gallons out of your car. Then you have to multiple 7.66666 by 2.48 and get $19.01 per week. but if i'm a typical american i go 350 miles per week and spend 19.28. now in a month i will go 345 x 4= 1380 which would be a full tank plus about half a tank. well i looked at all of the cars but i still like the one i have.

graduation car

the car I want for graduation is toyota prius. the reason I chose this car is because it has a 45 MPG gas mile rating and 20 gallons to a tank, plus it is safe and reliable. so it will only cost me $69.80 to fill up a tank.
