Question

Dana is the campaign manager for a candidate for governor. Through a commissioned poll, she discovers that the candidate's approval rating has changed from 70 to 88 percentage points, a gain of 18 percentage points. What was the percent change for the candidate's approval rating?

Answer 1

Answer:

25.71%

Step-by-step explanation:

Although the first instinct would be to say that his approval rating changed by 18%, the actual percent change for the candidate's approval rating is given by the difference between both polls (18%) divided by the candidate's approval in the first poll (70%):

$P=\frac{18}{70} =0.2571=25.71\%$

The percent change for the candidate's approval rating was 25.71%
