1. The problem asks: If Mrs. Mackle has 70 students, how many chose vanilla based on the graph data? 2. From the graph description, the bar for Vanilla reaches slightly above 45 students. We estimate the number of students who chose vanilla as approximately 47. 3. To find the proportion of students who chose vanilla, we use the formula: $$\text{Proportion} = \frac{\text{Number who chose vanilla}}{\text{Total students in graph}}$$ 4. The total number of students represented in the graph is the sum of students for all flavors: Vanilla \approx 47, Chocolate \approx 77, Strawberry \approx 60 Total = 47 + 77 + 60 = 184 5. The proportion of students who chose vanilla is: $$\frac{47}{184}$$ 6. Mrs. Mackle has 70 students, so the estimated number who chose vanilla is: $$70 \times \frac{47}{184}$$ 7. Simplify the fraction: $$70 \times \frac{\cancel{47}}{\cancel{184}}$$ No common factors to cancel, so calculate the decimal: $$70 \times 0.2554 = 17.88$$ 8. Since the number of students must be whole, we round to 18. **Final answer:** Approximately 18 students chose vanilla out of 70.
