Question

band members are selling magazines to raise $150 for a field trip. the bar graph below shows the amount six band members have collected so far. paul, jim, and dan are boys and jane, ma, and bryn are girls. by what percent of the total money raised so far do the girls exceed the boys? a. about 10% b. about 20% c. about 7% d. about 15%

Explanation:

Step1: Identify boys' and girls' amounts

Let's assume Paul, Jim, and Dan are boys and Jane, Mia, and Bryn are girls. From the bar - graph, Paul raised $25$, Jim raised $10$, Dan raised $20$, so boys' total is $25 + 10+20=55$. Jane raised $40$, Mia raised $15$, Bryn raised $10$, so girls' total is $40 + 15+10 = 65$.

Step2: Calculate the difference

The difference between the girls' and boys' amounts is $65 - 55=10$.

Step3: Calculate the total amount raised

The total amount raised is $55 + 65=120$.

Step4: Calculate the percentage

The percentage is $\frac{10}{120}\times100\%\approx8.33\%\approx 7\%$ (rounded to the nearest whole - number percentage).

Answer:

C. about 7%
