Answer: $0.0195
Step-by-step explanation: To find the price per ounce of apple juice, we need to divide the total cost by the number of ounces.
Price per ounce = Total cost / Number of ounces
Here, the total cost is $2.50 and the number of ounces is 128.
Price per ounce = $2.50 / 128 ounces
Price per ounce = $0.0195
Therefore, the price per ounce of apple juice is $0.0195, which is approximately 2 cents per ounce.
