Option B
7569 number of people are going to vote for the other candidate
<em><u>Solution:</u></em>
Given that candidate took a phone poll of 110 people
Of the 110 people polled, 87 said they would vote for the other person
There are 9570 people in the district
You can set up this problem like a proportion
Let "x" be the number of people who would vote for the other candidate
To solve proportions, you cross-multiply. This means you multiply the numerator by the other denominator, and the denominator by the other numerator
832590 = 110x
x = 7569
Thus 7569 number of people are going to vote for the other candidate
