A study is being conducted on air quality at a small college in the South.As part of this study,monitors were posted at every entrance to this college from 6:00 a.m.to 10:00 p.m.on a randomly chosen day.The monitors recorded the mode of transportation used by each person as they entered the campus.Based on the information recorded,the following bar graph was constructed. Approximately what percentage of people entering campus on this particular day arrived by car?

A) 9%
B) 31%
C) 53%
D) 62%

To find the percentage of people entering campus by car on this particular day, we need to add up the percentage of people who arrived by car for both faculty/staff and students categories. From the bar graph, we can estimate that approximately 47% of faculty/staff and 15% of students arrived by car. Adding up these percentages, we get 47 + 15 = 62%, which is closest to choice D. Therefore, the best choice is D, with the explanation that approximately 62% of people entering campus on this particular day arrived by car.
