Answer:

Option C.

Step-by-step 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 [tex]\frac{3x}{5}[/tex] >18

Now we multiply the inequality by 5

3x > 18 × 5

3x > 90

By dividing the inequality by 3

[tex]\frac{3x}{3}[/tex] > [tex]\frac{90}{3}[/tex] ⇒ x > 30

So number of students in the class are more than 30

Option C is the answer.
