No, it is not the same. Suppose the original price was $120.00. If I took 15% off of the regular price (15 / 100 (Equals) 0.15 x 120 (Equals) 18), the new price would be $18.00. Then if I take another 10% off from $18.00 (10 / 100 (Equals) 0.10 x 120 (Equals) 12), the next new price would be $12.00. Now if I took 25% off from $120.00 (25 / 100 (Equals) 0.25 x 120 (Equals) 30), the new price would be $30.00. So taking 15% off from a original price and another additional 10% off of the reduced price is different than taking 25% off from an original price.
