Some stores already do this for you by displaying the unit price next to the price tag but for the sake of this example, lets say there isn't one. I know a lot of you might know how to figure this out already but for those of you that don't, here is a simple way to figure out which one is the best deal between the two examples above.
What is the better deal between these two?
Deal #1: 12-PK/12 oz. - BEER for $13.99
Deal #2: 6-PK/12.oz. - BEER for $5.99
First, we must figure out how many total ounces they are selling for each deal. The first deal is 12 beer at 12 ounces each so in order to figure out the total ounces we must multiply BEER x OUNCES per beer. The Math should look like so: 12(beers)x12(ounces)=144(ounces of beer). So now that we have the total ounces, we need to take that amount and divide it by the cost to figure out how much we are paying per unit. This math should look like this: $13.99/144(ounces)=0.0972 (price per unit).
If you want to know how much you're paying per beer bottle, you can divide $13.99 by 12 beers which equals $1.16/each beer.
Not bad! Now lets look at deal #2 with the same math.
You take 6(beers)x12(ounces)=72(ounces of beer)
Then you take $5.99/72(ounces of beer)=0.083 (per price unit)
So if you calculate $5.99/6 beers, you re paying $0.99/each beer.
So you figured it out the best deal! Congrats! Now grab two of those 6 packs of your second favorite beer and enjoy! You wallet will thank you.
