Step-by-step explanation:
The student's question regards the conversion of different units of liquid volume. Specifically, Jane has a 40-ounce mixture of apple juice and seltzer that is 30% apple juice, and we need to determine how many ounces of apple juice are in the mixture.
To solve this, we need to calculate 30% of 40 ounces:
First, convert the percentage to a decimal by dividing by 100: 30% / 100 = 0.3.
Next, multiply the total ounces by the decimal to find the amount of apple juice: 0.3 × 40 ounces = 12 ounces.
Therefore, there are 12 ounces of apple juice in the mixture.
The correct option is 1.
