C.

Answer 1

C. 7.68 x 107

Explanation:

To solve this problem, we can start by multiplying the number of students in the local school system by 480, since there are 480 times more students in public schools in the United States.

1.6 × 10^5 * 480 = 7.68 × 10^7

Therefore, the approximate number of students enrolled in public schools in the United States is 7.68 × 10^7, which corresponds to choice (C).
