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, mia, 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 money raised by boys and girls

Boys (Paul, Jim, Dan): \(15 + 10+20 = 45\) dollars. Girls (Jane, Mia, Bryn): \(25+30 + 15=70\) dollars.

Step2: Calculate total money raised

Total money raised is \(45 + 70=115\) dollars.

Step3: Calculate the difference

The girls - boys difference is \(70 - 45 = 25\) dollars.

Step4: Calculate the percentage

The percentage is \(\frac{25}{115}\times100\%\approx21.74\%\approx20\%\) (rounded to the nearest 10 - percent).

Answer:

A. about 20%
