Question

Last year a poll of 1,000 voters conducted by the staff of Senator Chun found that 522 people approved of the job the senator was doing. This year, a new poll of 1,000 voters shows that 423 people approve of the senator's performance. Find the percent of change in the number of voters who approved of the senator's performance, and identify it as an increase or decrease.

A 19%, increase
B 23.4%; decrease
C 23.4%, increase
D 19%; decrease​

Answer 1

19% decrease

Explanation:

First, find out how much it decreased by. 522 - 423 = 99. Then, since it decreased by 99/522 you find the percent this is equal to, which would be

18.96%. = about 19%

It is going down, so it's decreasing
