Answer:
To determine the number of students who voted for Candidate C, we need to first find what percent of the total votes they received. Looking at the graph, it appears that Candidate C received approximately 40% of the votes.
To find out how many students this represents, we can set up a proportion:
40% = C/150
Where C is the number of votes received by Candidate C.
To solve for C, we can cross-multiply:
0.4 x 150 = C
C = 60
Therefore, 60 students voted for Candidate C.
Charlotte's mistake was assuming that the percentage of votes for Candidate C directly corresponded to the number of students who voted for them. It's possible that more than one student voted for each candidate, and the percentage of votes represents the proportion of all votes each candidate received.
