A poll was taken to explore the relationship between age and support for a candidate in an election. The results of the poll are summarized in the table. How many people above age 30 are for the candidate?
To determine how many people above age 30 are for the candidate, we need to add up the number of supporters in the 31-40 age group, the 41-50 age group, and the 51-60 age group.
Number of supporters in the 31-40 age group: 25
Number of supporters in the 41-50 age group: 30
Number of supporters in the 51-60 age group: 20
Total number of people above age 30 who are for the candidate:
25 (31-40) + 30 (41-50) + 20 (51-60) = 75
Therefore, there are 75 people above age 30 who support the candidate.
