Answer:
Brand A costs approximately $0.21 per ounce
Brand B costs approximately $0.18 per ounce
Step-by-step explanation:
the rate can be regarded as the change in one entity with respect to the other
From the question, we know brand A
$ 2.55 for 12 ounces of juice, to Know the cost of single once of the juice is
($ 2.55/12ounce)
=$ 0.2125
But the conversation rate for dollar to cent is (1 dollar = 100 cents)
Then to convert $ 0.2125 to cent, we can say
1 dollar = 100 cents
$ 0.2125 =X cent , if we cross multiply we have
= 21.25 cents
Which is approximately 21 cents.
From the question, Brand B cost $ 1.45 for 8 ounces of juice.
to Know the cost of single once of the juice is ( $ 1.45/8 ounce)
=$ 0.18125
We can convert to cent like we did above
1 dollar = 100 cents
$ 0.18125 =X cents, if we cross multiply, we have
= 18.125 cents
which is approximately: 18 cents
Therefore, the true statement about the unit rate are"Brand A costs approximately $0.21 per ounce
Brand B costs approximately $0.18 per ounce"
