Given 40 ounce mix = Apple juice + seltzer

Now 40 ounces contain 30% apple juice i.e. 12 ounce and seltzer will be 28 ounces.

We are told that 10 more ounces of apple juice ( 100% ) is added to mixture, then total mixture will be 50 ounces.

We want seltzer percentage in the total juice and since only 100% apple juice is added, seltzer concentration doesn't get affected.

So. 28 / 50 => 0.56

Explanation

Originally, Jane had a 40-ounce mixture of apple and seltzer that was 30% apple. Since 0.30(40) = 12, 12 ounces were apple and 28 ounces were seltzer.

When Jane pours 10 more ounces of apple juice into the mixture, it yields a mixture that is 50 ounces total, still with 28 ounces of seltzer. Now, the percent of seltzer in the final mixture is $$\frac{28}{50} \times 100 =56%$$.

Hence option D is correct!
