Formula for Percent Decrease: [tex]\text {Percent Decrease} = \frac{\text {Decrease}}{\text {Old Price}}~*~100~\text {percent}[/tex]

Subtract,
135 - 108 = 27
Fill into formula,
[tex]= \frac{\text {27}}{\text {135}}~*~100~\text {percent}\\= \frac{\text {1}}{\text {5}}~*~100~\text {percent}\\= 0.20~*~100~\text {percent}\\= 20~\text {percent}[/tex]

Hence, the percent decrease is 20%!

Between June and July, sales at the store decreased by 20%.
The sales reduced from 135 copies in June to 108 copies in July.
In order to find the percent decrease, first find the absolute decrease:
= June sales - July sales
= 135 - 108
= 27 copies
The percentage decrease is:
= Absolute decrease / June sales x 100%
= 27 / 135 x 100%
= 20%
In conclusion, the percent decrease in sales was 20%.
