The principal at a middle school gave a survey to randomly selected students, asking which activity of the after-school program they were attending.
If the number of students who participated in art decreased by 5, how many total students would the principal have expected in order to keep the number of students who participated in art proportional to the total number of students surveyed?
1: 64 students; because the new total number of students is now 64. The current total number of students is 80. There should be 16 fewer total students in the after-school activities to keep the number of students in the art activity proportional to the total number of students in the after-school activities.
2: 46 students; because the new total number of students is now 46. The current total number of students is 80. There should be 34 fewer total students in the after-school activities to keep the number of students in the art activity proportional to the total number of students in the after-school activities.
3: 69 students; because the new total number of students is now 69. The current total number of students is 80. There should be 21 fewer total students in the after-school activities to keep the number of students in the art activity proportional to the total number of students in the after-school activities.
pt 2:If the middle school had 2,000 students, how many students out of the total student population would she have expected to participate in each of the following activities?
Sports: 375,250,750,625
Music: 375,250,750,625
Art: 375,250,750,625
NONE: 375,250,750,625
