Cora is buying a $109 dress for the school dance. She has two coupons, one for $10 off and one for 15% off. If she is allowed to use both, is it better to take the $10 off first, then the 15%? Or is it better to take the 15% off first, then the $10 off?
Take the $10 off, then the 15% off
Take the 15% off, then $10 off
