Answer 1

To find an expression that is equivalent to the one Tyrone wrote, we need to consider the operation he performed. Tyrone is calculating the average drop in enrollment by dividing \(-3245\) (the total drop in enrollment) by \(11\) (the number of years).

The expression he wrote is:

\[ -3245 \div 11 \]

This can also be written in fraction form as:

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

Now let's analyze the answer choices:

A. \(-3245 - 11\)
B. \(-\frac{3245}{11}\)
C. \(-\frac{-3245}{11}\)
D. \(-3245 - 11\)

The correct equivalent expression to \(-3245 \div 11\) is option B:

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

So, the answer is:

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