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%):

[tex]P=\frac{18}{70} =0.2571=25.71\%[/tex]

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