$2 bucks la, & U1 g, X: V4 O% u! Iassume he has $9 at the beginning, minus $8 for the first purchase and sold it for $9, his balance should be $10, then he used $10 to purchase, the balance is $0, afterward, he got $11 back, his final balance would be $11, $11 - $9 = $2 in total作者: tcyong80 時間: 2007-10-27 05:19 PM
