Which Is The Better Deal?

     The cost of a 12 pack of Mountain Dew cost 11.99. This means the cost for one soda would be $1 based on the price. This can contains 8 ounces. If you divide 1 by 8, you get 0.125. In money, this is 12.5 cents. The cost for a 1 liter bottle of soda online is about $6 dollars. A one liter bottle contains 33.8 ounces. The cost for a one ounce is about 10 cents. Another factor to consider when you are buying is to include the fact that the 12 pack gets charged Crv, which cost 10 cents per can, therefore the cost of the 12 pack is increased to 11.99.

     Therefore, the better deal would be to buy one liter bottles since the cost is less per ounce, and if you would buy a liter of soda using the first amount would be about $4.23, and the cost for the second amount would be $3.38. The difference between these two cost is $0.85. Clearly, the better deal is the second one, and you are being ripped off if you buy the 12 pack.

What I Remember Most In Algebra From the First Semester

     I remember substitution the most. Substitution is when you have two equations, and you want to find the solution ( intersecting points on a graph). If the first equation was y=2x-5, and the second equation was y=-4x+7. If y=2x-5, and y also equals -4x+7, then -4x+7 must equal 2x-5. So it would be turned into a balance problem. -4x+7=2x-5 would be the balance equation. To find x and y's values you have to use this method. The first step in this equation would be to get rid of -4x. How do you get rid of a negative number? You get rid of a negative number adding it's absolute value which is +4x, and if we add 4x to one side, we also have to add it to the other side. Now the equation looks like this 7=6x-5. Now we want to have 6x by itself, so we will get rid of -5 by adding 5. Remember, if you add to one side, you also have to add to the other side. Now the equation looks like this 12=6x. We do not want to know what 6x equals, we want to know what 1x equals. We will now divide both sides by 6 which will give us 2=x. We will now plug in 2 for x. Now the original equation looks like this y=2(2)-5. 2*2 is 4, and 4-5 is -1; y is -1. The point where they will intersect on a graph is (2,-1).

     When we were reviewing this in Algebra, many kids reactions were that they had forgotten how to substitute. I was one of the kids who were most confused.After Mr. Erickson reintroduced this concept to us, it all made sense.
