A promotional sale at a department store offers 25% off the sale price. The sale price is 25% off the regular price. Is this the same as a sale that offers 50% off the regular price? (Try both with a coat whose original cost was $100)

It is not the same.

It is not the same because after doing the 25% the first time you will get a different number to be multiplied by 25%. But with 50% you only do it once to one number only

50%:

100 x 0.5 = 50

100-50 = 50

final price: $50

25% then another 25%:

discount off original price

100 x. 25 = 25

100-25 = 75

discount off sales price

75 x. 25=18.75

75-18.75 = 56.25

final price $ 56.25

AS you can see it is not the same

The answer is no it is not
