$0.50
$0.47
$0.40
$0.37

Explanation:

Step1: Calculate cost per ounce of juice A

The cost of a 12 - ounce bottle of juice A is $5.64. So the cost per ounce of juice A is $\frac{5.64}{12}= 0.47$ dollars per ounce.

Step2: Calculate cost per ounce of juice B

Juice A costs $0.10 more per ounce than juice B. Let the cost per ounce of juice B be $x$. Then $x + 0.10=0.47$. Solving for $x$, we get $x=0.47 - 0.10 = 0.37$ dollars per ounce.

Answer:

$0.37$
