Class Ranking Total Student Calculation
This problem requires calculating the total number of students in a class using the rank of one student from both the top and the bottom.
Given information:
- Mona's rank from the top: $9^{\text{th}}$
- Mona's rank from the bottom: $36^{\text{th}}$
Formula for Total Students
To find the total number of students in the class, we can use the formula:
$ \text{Total Students} = (\text{Rank from Top}) + (\text{Rank from Bottom}) - 1 $We subtract 1 because the student (Mona, in this case) is counted in both the rank from the top and the rank from the bottom.
Step-by-Step Calculation
- Substitute the given ranks into the formula: $ \text{Total Students} = 9 + 36 - 1 $
- Add the ranks together: $ \text{Total Students} = 45 - 1 $
- Subtract 1 to get the final total count: $ \text{Total Students} = 44 $
Thus, there are 44 students in the class.
