Correct answer: C. 639
- A. 587
- B. 613
- C. 639
- D. 665
Explanation
To determine the total number of students in the high school, set up a proportion using the information that the 142 band students represent two-ninths of the total students. Cross-multiply to solve for the unknown:(142 band students) / (Total students) = (2/9)142 * 9 = Total students * 21,278 = Total students * 2Total students = 1,278 / 2Total students = 639Therefore, the correct answer is 639. Option A, B, and D are incorrect as they provide different values obtained from incorrect calculations.
