Of the students at Milton middle school 91 are girls, if 35% of the students are girls, how many total students are there at Milton middle school

195
130
260
325

Let x be the total number of students at Milton middle school.

If 35% of the students are girls, then there are 0.35*x girls at the school.
Since 91 girls are at the school, then 0.35*x = 91.
Dividing both sides of the equation by 0.35, we get x = 91 / 0.35 = 260.
Therefore, the total number of students at Milton middle school is 260.
The correct answer is 260.
