Answer:
60%
Step-by-step explanation:
Let the total number of people polled to vote be 1000
80% said they would vote for him
That is 800
20% said they would not vote for him
That is 200
Out of the 800, 70% actually voted
That will be ;
70/100 * 80 = 560
Also, 20% of the 200 that said they would not vote actually voted
That will be ;
20/100 * 200 = 40
Total is thus;
569 + 40 = 600
% is 600/1000 = 60%
