Solution

First, let's find out the price per bottle for each package:

For the 6-bottle package: 13.08÷6=13.08 ÷ 6 = 2.18 per bottle

For the 4-bottle package: 11.28÷4=11.28 ÷ 4 = 2.82 per bottle

So, the 6-bottle package has a better price per bottle.

Now, let's calculate how much Brenda would spend for 12 bottles with each package:

With the 6-bottle package: 2 packages × 13.08perpackage=13.08 per package = 26.16

With the 4-bottle package: 3 packages × 11.28perpackage=11.28 per package = 33.84

Finally, let's find out how much Brenda saves by buying 12 bottles at the better price:

33.84(pricefor12bottleswiththe4bottlepackage)33.84 (price for 12 bottles with the 4-bottle package) - 26.16 (price for 12 bottles with the 6-bottle package) = $7.68

So, Brenda saves $7.68 by buying 12 bottles of water at the better price.
