36=(0.12)n
n=300
300 students were surveyed.
That's the way I answer in my country but I'm not sure about this solution is correct in your school or not.

Answer:

300 students were surveyed.

Explanation:

We are given the following information in the question:

Percentage of students at Rockwood Junior High School who speak Spanish = 12%

Number of students at Rockwood Junior High School who speak Spanish = 36

We have to find the total number of students who surveyed:

Formula:

Let x be the total number of students who were surveyed.


12\% \text{ of }x = 36\\\\\displaystyle(12)/(100)* x = 36\\\\x = (36* 100)/(12)\\\\x = 300

Thus, 300 students were surveyed.
