Aclass of 40 students elected a class president. there were 12 votes for candidate a, and 18 votes for candidate bb. the rest of the class did not vote. which expression gives the percent of voters who voted for candidate a?

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
