Answer 2

Calculation of the Number of Students in the Class

To determine the number of students in the class, we can use the information provided in the question. According to the question, 12% of the students did not solve the problems, 32% solved the problems with errors, and the remaining 14 students solved the problems correctly.

Let's assume the total number of students in the class is x.

- 12% of the students did not solve the problems, which means 0.12x students did not solve the problems. - 32% of the students solved the problems with errors, which means 0.32x students solved the problems with errors. - The remaining 14 students solved the problems correctly.

To find the total number of students in the class, we can set up the following equation:

0.12x + 0.32x + 14 = x

Simplifying the equation:

0.44x + 14 = x

Subtracting 0.44x from both sides:

14 = 0.56x

Dividing both sides by 0.56:

x = 14 / 0.56

x ≈ 25

Therefore, there were approximately 25 students in the class.
