A twelve pack ( 12 oz. ) for mountain Dew cost $12.99 and a liter Mountain Dew soda (33.8 oz. ) costs $1.50. So we are trying to figure out which one is better to buy and why. To find the better price we must do some typical math problems. First we have to divide 12.99 by 12 which would be the price and the cans. That way we can see how much a can costs so that it will be easier to solve. The answer is about $1.08 per can so now it will be easier to do the rest.
Then we have to divide our price per can by the ounces in a can to get the price per ounce. So we have to divide 1.08 by 12. 1.08 is the price of the can and 12 is the ounces in the can. That is $0.09 per ounce. Next we have to find the price per ounce of the liter soda. Our first step is to divide the price by the ounces in the liter. In this case it is 1.50 by 33.8! The answer is about $0.05 per ounce.
Finally all we have to do is compare. So there you have it, a liter soda is cheaper than a twelve pack. You actually save a little more than four cents for every ounce. So the next time you want to save you better buy yourself a liter soda. That is how you find the difference in two prices!!
