Sally has a coupon that she can use in addition to the sales at a particular store. Excited to stock up, she immediately finds two sweaters that are each 30% off and decides to use her “buy one get one half off” coupon to save even more. If the two sweaters were originally the same price, what single percent discount would have resulted in the same savings as Sally’s combined discount?

Please and Thanks!

    Let's assume the sweaters are $10 each. To start with, Sally gets $3 off each because of the 30% discount....$6 off total. She gets half off one of the shirts, now priced at $7, which is a savings of $3.50. In total, she saved $9.50, which is a 47.5% discount in the end.
