1. **State the problem:** We need to find which class sold the most magazines per student on average. 2. **Formula:** The average magazines sold per student for each class is calculated by dividing the total magazines sold by the number of students: $$\text{Average per student} = \frac{\text{Number of magazines}}{\text{Number of students}}$$ 3. **Calculate for each class:** - Ms. Barton's class: $$\frac{110}{22} = \cancel{\frac{110}{22}} = 5$$ - Mrs. Garza's class: $$\frac{189}{27} = \cancel{\frac{189}{27}} = 7$$ - Mr. Wyatt's class: $$\frac{192}{24} = \cancel{\frac{192}{24}} = 8$$ - Mr. Conley's class: $$\frac{174}{29} \approx 6$$ 4. **Compare the averages:** - Ms. Barton's class: 5 magazines per student - Mrs. Garza's class: 7 magazines per student - Mr. Wyatt's class: 8 magazines per student - Mr. Conley's class: approximately 6 magazines per student 5. **Conclusion:** Mr. Wyatt's class has sold the most magazines per student on average. **Final answer:** Mr. Wyatt's class
