Question

You can buy shampoo in a 5-ounce bottle for $2.49 or in a 15-ounce bottle for $9.69.

Answer 1

The 5 ounce bottle for $2.49 is a better deal because the unit price is .49 cents PER ounce, where as the 15 ounce bottle for $9.69 is .64 cents PER ounce.

$9.69/15 = $0.64
$2.49/5 = $0.49

Answer 2

Assuming you want more for less..

By getting 3 5-ounce bottles you get the same amount as a 15-ounce bottle.

However for 3 5-ounce bottles it would cost you 7.47 $ cents. While a 15-ounce battle would cost you 9.69 $ (2.22 $ more)

So in buying 3 5-ounce bottles you save 2.22 dollars in comparison to a 15-ounce bottle.
