Hello!
First you have to find how far the price went down
You do this by subtracting the whole price by the sale price
18.00 - 14.40 = 3.6
Now you find what percent this is to 18.00
You do this by doing how far the price went down over the whole price
3.6/18 = 0.2
The sale discount was 20%
the answer is 20%
Hope this helps!
