Question 143146
Saying it in a simple way that Mrs. Martinez has a total of 45% off the ORIGINAL PRICE(which is the sale price  right?).
So her final price is simply 55% off the original price (100%-45%)
In doubt?
Get an example, let's say orig price is $100. She get 25% off that, PLUS 20% of the coupon, total 45% off the orig $100 equals $55 --- and this is 55% of the original price.
thank you,
