Brand A cost's approximately $0.21 per ounce and Brand B costs approximately $0.18 per ounce.
My Work:
Brand A: 2.55/12 = 0.2125 (approximately $0.21)
Brand B: 1.45/8 = 0.18125 (approximately $0.18)

Answer:

The statement which is true about the unit rate is:

  • Brand A costs approximately $0.21 per ounce, and Brand B costs approximately $0.18 per ounce.

Step-by-step explanation:

Unit Rate--

It the rate which is used to find how much does one quantity corresponds to the one unit of the second quantity.

Brand A:

It cost $ 2.55 for 12 ounces of juice.

This means that the cost of 1 ounces of juice will be: $ 2.55/12=$ 0.2125

Now, we know that:

 1 dollar = 100 cents

Hence, $ 0.2125 = 21.25 cents

which to the nearest cents is: 21 cents.

Brand B:

It cost $ 1.45 for 8 ounces of juice.

This means that the cost of 1 ounces of juice will be: $ 1.45/8=$ 0.18125

Now, we know that:

 1 dollar = 100 cents

Hence, $ 0.18125 = 18.125 cents

which to the nearest cents is: 18 cents.
