A survey of students' favorite sports showed 15 chose basketball, 10 chose soccer, 8 chose baseball, and 7 chose track. What percentage of students chose basketball?

✓ Correct Answer: Option D

Total students = 15 + 10 + 8 + 7 = 40. Percentage for basketball = (Number of basketball students / Total students) * 100 = (15 / 40) * 100 = 0.375 * 100 = 37.5%.
