44.83%

33.72%

23.39%

55.17%

Answer 1

The correct answer is: 23.39%

Explanation:

To determine the percentage of underclassmen interested in taking a Mandarin course next year, we need to calculate the ratio of the number of underclassmen interested in Mandarin (145) to the total number of underclassmen (620) and then multiply by 100 to get the percentage.

(145 / 620) * 100 ≈ 23.39%

Therefore, approximately 23.39% of the underclassmen have an interest in taking a Mandarin course next year.
