D.

Answer 1

Tyrone's expression for calculating the average drop in enrollment is:

\[ -3245 \div 11 \]

To express this division with the same elements in a different form, we can recognize that dividing by a number can be interpreted as multiplying by the reciprocal of that number. Therefore, the equivalent expression can be written as:

\[ -3245 \cdot \frac{1}{11} \]

This could also be expressed compactly as:

\[ -\frac{3245}{11} \]

From the options provided, the one that matches this interpretation is:

B. \(-\frac{3245}{11}\)

Thus, the correct answer is B.
