178

1 answer

The total amount of money Ava paid can be represented by the equation 120 + 2.50x = 325, where x is the number of students who attended the dance.

Subtracting 120 from both sides, we get 2.50x = 205.
Dividing by 2.50 on both sides gives x = 82.

Therefore, 82 students attended the dance.

So, the correct answer is 82.
