### Prealgebra Exam Scores

The bar graph displays the distribution of exam scores for a prealgebra class. The x-axis represents the score intervals, and the y-axis shows the frequency, which indicates the number of students who scored within each range.

- **Score Range 70.5 - 75.5**: 13 students
- **Score Range 75.5 - 80.5**: 7 students
- **Score Range 80.5 - 85.5**: 6 students
- **Score Range 85.5 - 90.5**: 10 students
- **Score Range 90.5 - 95.5**: 19 students
- **Score Range 95.5 - 100.5**: 9 students

This graph helps in understanding the performance distribution, indicating more students scored in the 90.5 - 95.5 range compared to other ranges. The objective here is to find the upper class limit of the first class.
