A.40 B.60 C.80 D.88 E.90 let people eligible to vote = y people actually voted = x Democratic = 0.55x Republican = 0.35 x total voters = 0.90 x hence 0.10x voters who voted didnt voted for D and R. now, 0.10 x = 0.08 y => x/y = 8/10 hence 80% Hence C

Hi, I think this is the way how to solve this problem Democractic : 55 Republican : 35 Total Eligible Population : x Neither : 0.08x (Its an election so you cant have both ) => 55+35+0.08x = x 90 = 0.92 X X = 100 Thus the percent of people eligible to vote actually voted in the elections = (55+35)/100 =>90/100 = 90% Thus E

Hi,
I think this is the way how to solve this problem
Democractic : 55 Republican : 35 Total Eligible Population : x Neither : 0.08x (Its an election so you cant have both )
=> 55+35+0.08x = x 90 = 0.92 X X = 100
Thus the percent of people eligible to vote actually voted in the elections = (55+35)/100 =>90/100 = 90%
Thus E That's not correct. If you are doing that way then you should have 55%+35%+0.08x% = 100%, because 55%, 35% and neither=0.08x% together must sum up to 100% (all that voted). 55+35+0.08x = 100 > x=125 > voted/eligible=100/125=0.8. Answer: C.

Hi,
I think this is the way how to solve this problem
Democractic : 55 Republican : 35 Total Eligible Population : x Neither : 0.08x (Its an election so you cant have both )
=> 55+35+0.08x = x 90 = 0.92 X X = 100
Thus the percent of people eligible to vote actually voted in the elections = (55+35)/100 =>90/100 = 90%
Thus E That's not correct. If you are doing that way then you should have 55%+35%+0.08x% = 100%, because 55%, 35% and neither=0.08x% together must sum up to 100% (all that voted). 55+35+0.08x = 100 > x=125 > voted/eligible=100/125=0.8. Answer: C. Hi Bunuel.. Why are we adding neither part into the equation above ? lets say 100 people voted.. so 55 + 35 = 90 voted say x people are eligible to vote : .08x didn't vote for any of them , >> so why are we adding it to ones who voted ??? Please help !!
