Taking successive discounts of 15% off and then 25% off is the same as taking a one time discount of 40%.
true or false.

Let's try it.

Item A is 100$ and is 40% off. 100 * 40% = 40
100 - 40 = 60
Final Price: 60$

Item B is 15% off then 25% off, and is also 100 usd
100 * 15% = 15
100 - 15 = 85
85 * 25% = 21.25
85 - 21.25 = 63.75

No, 40% off is not the same as 25% the  15% or 15% then 25%

False, because you calculating % from number you working on, not from number you started with
