Show answer & explanation
Correct answer: C
Key idea: compute the total students before and after admitting new students; the difference is the number of new students.
Find the initial number of sections: 16 − 3 = 13.
Compute the initial total students: 13 × 32 = 416.
Compute the final total students after admission: 16 × 30 = 480.
New students admitted = final total − initial total = 480 − 416 = 64.
Answer: 64 new students.
