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

\frac{87}{110} = \frac{x}{9570}

To solve proportions, you cross-multiply. This means you multiply the numerator by the other denominator, and the denominator by the other numerator

87 \times 9570 = 110 \times x

832590 = 110x

x = 7569

Thus 7569 number of people are going to vote for the other candidate

to figure this out, lets understand how decimals work

a decimal number in the tens place before the decimal

  ↓ here

0.00

that number will be the same number as the numerator or top number of a fraction in tenths

↓ here

0/10

so say it was 4/10 we needed to find, we would look on the number line for 0.40 like in answer choice B (NOT THE CORRECT ANSWER FOR THIS PROBLEM)

hope this helps you out on your work :)
