Answer 1

Answer:
________________________________________________________
"Brand B" costs 2 cents more per fluid ounce than "Brand A". and:

"Brand A" costs 2 cents less per fluid ounce than "Brand B" .
________________________________________________________
Step-by-step explanation:
_________________________________________________
Start with "Brand A" :
_________________________________________________
$ 1.28 / (8 fl. oz) = 1.28 ÷ 8 = 4/5 = $0.16 / fl. oz. ;

[ $0.16 per fluid ounce ] .
_________________________________________________
Now, "Brand B" :
_________________________________________________
$ 1.68 / (12 fl. oz.) = 7/50 = $0.14 / fl. oz.

[ $0.16 per fluid ounce]
__________________________________________________

So, "Brand B" costs more, per fl. oz., than "Brand A".
__________________________________________________

"Brand B" costs: 16 cents per fl. oz.

"Brand A" costs: 14 cents per fl. oz.
_______________________________________________________

16 cents − 14 cents = 2 cents .
_______________________________________________________
So,

"Brand B" costs 2 cents more per fluid ounce than "Brand A". and:

"Brand A" costs 2 cents less per fluid ounce than "Brand B" .
