Question

use the information shown in the graph. the graph represents a survey of undergraduates enrolled in college in the 2003-2004 school year.
hours per week worked by college
students ages 22 or younger
21-34 hours 21.5%
35 or more hours 18.9%
did not work 25.4%
1-20 hours 34.2%
approximately what percentage of students worked more than 21 hours per week? round each term to the nearest whole percent before calculating your answer.
the percentage of students who worked at least 21 hours per week is approximately %.

Explanation:

Step1: Round the percentages

Round \(21.5\%\) to the nearest whole percent: \(22\%\) (since \(0.5\) rounds up).
Round \(18.9\%\) to the nearest whole percent: \(19\%\) (since \(0.9\) rounds up).

Step2: Add the rounded percentages

To find the percentage of students who worked more than 21 hours per week, we add the percentages for "21 - 34 hours" and "35 or more hours".
So, \(22\% + 19\% = 41\%\).

Answer:

41
