To rent a building for a school dance, Ava paid $120 plus $2.50 for each student who attended, if she paid a total of $325, how many students attended the dance?

Question

130

82

48

178

Answer 1

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.
