New Gas Price Cost

Part One
If the gas prices are $2.20 you would do the same thing as you did in the other paragraph except you replace the old gas price with the new one. you would multiply the cost with the amount of gallons it holds and you would get $29.70. After that you would subtract the numbers to see how much you saved. $39.96-$29.70=$10.26 so I saved over $10. answer: $10.26

Part Two
On that website I learned a lot like why gas prices are suddenly falling again it is because next month there will be a greater supply of gas because of a hurricane coming upstream. I also learned that every one dollar decrease in the gas price it saves $1billion for consumers. The economy is headed downward though.

Poly-What?

In the movie I learned that 4x+3y can't be reduced any farther because the are unlike terms before I thought that it would be reduced to 7xy. It also helped make polynomials a little more clear. And I learned where the name polynomial came from!
