Hi there!
To find the percent discount, we need to divide the new price by the original price without the discount:
18 / 25 = 0.72
Now, we convert this into a percentage, so we can find the <em>percent </em>discount:
0.72 = 72%
Now, we subtract from 100%:
100% - 72% = 28%
So, the answer is 28%.
Hope this helps!
