Answer:
C. 50
Step-by-step explanation:
Let the total number of students in the science club be "x".
We are given that 10 students represent 20% of the total number of students in the science club, which can be expressed mathematically as:
10 = 0.2x
To solve for x, we can divide both sides of the equation by 0.2:
10/0.2 = x
Simplifying, we get:
50 = x
Therefore, the total number of students in the science club is 50.
