The circle graph above represents the results of the 8th grade student body president elections. If 500 students voted, how many more students voted for Lisa than Harvey?
_______

2 answers

27% = 27 / 100 = 0.27

Lisa = 0.27 ∙ 500 = 135 votes

12% = 12 / 100 = 0.12

Harvey = 0.12 ∙ 500 = 60 votes

135 - 60 = 75
Thank you so much!
