Find the percent of the increase or decrease.
the percent is lower which is 40%
Set it up in words:
4005 is what percent of 4500?
Now make the words into numbers:
If you don't get it please let me know. :)
If 4005 is 89% of 4500, then the percent decrease must have been 100 - 89 = 11%. Another way of doing the same thing is:
difference is decrease of 4500-4005 = 495.
[495/4500] x 100 = 11%
Oh right, sorry forgot the last step
