## OPTION NUMBER TWO

A Nestle Pure Life Purified Water 15 pk 16oz is 2.59 at Target.

## HOW CAN WE FIND OUT WHICH IS THE BETTER BUY?

To find which is the better buy you can use unit rate. To find unit rate you can divide the amount of all the water bottles by how many bottles, so you can find how much is one water bottle. Once you know how much each water bottle is you can compare and see which ones cheaper, which would be the best buy.

## PROcedure

First I set up the problem in proportions. Then I divided the cost of the first option by 24 because that's how many water bottles there were. Lastly I rounded my answer.

## PROCEDURE

First I set up the problem in proportions. Then I divided the cost of the second option by 15 because that's how many water bottles there were. Lastly I rounded my answer.
So now that we know what each unit rate is we can conclude that option is better, because we know option one's unit rate is .15 and options two's unit rate .17. Obviously .15 is lower than .17 so option one is the better deal.
