1. **Stating the problem:** We have a histogram showing the frequency of students with different amounts of money. We need to find: a) The number of students with under 10 dollars. b) The percentage of students with over 20 dollars. 2. **Analyzing the histogram data:** - Frequency for under 10 dollars is about 60. - Frequencies for other ranges (approximate from histogram): - 10 to 20 dollars: about 50 - 20 to 30 dollars: about 40 - 30 to 40 dollars: about 30 - 40 to 50 dollars: about 20 - 50 to 60 dollars: about 10 - 60 to 100 dollars: about 0 3. **Calculating total number of students:** $$\text{Total} = 60 + 50 + 40 + 30 + 20 + 10 + 0 = 210$$ 4. **Answering part (a):** Number of students with under 10 dollars is approximately 60. So, the closest answer is **C. 60**. 5. **Answering part (b):** Students with over 20 dollars include frequencies for 30-40, 40-50, 50-60, and 60-100 dollar ranges: $$30 + 20 + 10 + 0 = 60$$ Percentage: $$\frac{60}{210} \times 100 = \frac{60}{210} \times 100 \approx 28.57\%$$ This is about 30%. So, the closest answer is **A. about 30%**. **Final answers:** - a) C. 60 - b) A. about 30%
