If you write it as rate equivalences you got something like:

100/3200=x/2464

solving x you can find:

x=(100∗2464)/3200

x=77

We've found that only 77% of newsletters are in circulation, the percent of decrease is:

100−77=23

Wait so I did this problem but I got 77% and that was wrong. but I guess I just forgot that last step! so the answer is 23 right?

anonymous · Answer

yes

Alternatively, subtract beginning value 3200 from end value 2464 to obtain the decrease (a negative quantity), and divide that by 3200, and multiply the result by 100%.
