Answer:

The correct answer is:

C. 50

Step-by-step explanation:

To determine the total number of students in the class, given that 40% of the students can ride a roller coaster and that 20 students ride the roller coaster, we can set up the following equation:

Let x be the total number of students in the class.

Given that 40% of the students ride the roller coaster, we can write:

\(\[0.40x = 20\]\\Now, solve for x:\[x = \frac{20}{0.40}\]\[x = \frac{20}{0.4}\]\[x = 50\]\)

Thus, the total number of students in the class is 50.

Therefore, the correct answer is:

C. 50
