Question 964062: In a survey, 61% of the people asked said they would vote yes for the town budget. The margin of error is 2.5%. The inequality |n - 61| ≤ 2.5 can be used to find the range of votes likely to vote yes for the budget
Which shows the solution to this inequality?
A) 58.5 ≤ n ≤ 61
B) 58.5 ≤ n ≤ 63.5
C) 61 ≤ n ≤ 63.5
D) 2.5 ≤ n ≤ 63.5

This means that either or
Let's take first
add 61 to each side
Now the second equation,
multiply each side by -1 which will change the direction of the inequality.
add 61 to each side
So we have and
which can be rewritten
