Two stores carry a similar stereo for the same original price of $573. Store A offers a 25% discount and Store B sells the stereo for $446.94. Which store gives the bigger percent discount? Justify your answer by determining the sale price for each store.

A ... $573 * .75 = s.p.

B ... (573 - 446.94) / 573 = % disc.
