Answer 2

Option C.

Explanation:

More than 18 students n an algebra class pass the first test and this number is about 3/5th of the class.

Let total number of students in class = x

so 3/5th of x > 18

Or
`(3x)/(5)` >18

Now we multiply the inequality by 5

3x > 18 × 5

3x > 90

By dividing the inequality by 3

`(3x)/(3)` >
`(90)/(3)` ⇒ x > 30

So number of students in the class are more than 30

Option C is the answer.
