QUESTION THREE:


The answer is no because :
First, pretend you have 100 dollars.
When you take 15 percent off it equals to 85; so now you have 85 dollars left.
[ $100 - 15 % = 85 ]
Then when you take an additional 10 % off from 85 you get :76.5
[
85 / 100 0.85 x 10 8.5
$85 - 8.5 = 76.5 ]

When you take 25 % off from $100, you get $75.
