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 2

Answer:

300 students were surveyed.

Step-by-step 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.

$12\% \text{ of }x = 36\\\\\displaystyle\frac{12}{100}\times x = 36\\\\x = \frac{36\times 100}{12}\\\\x = 300$

Thus, 300 students were surveyed.
