Xiao Wang fell in love with a book and a picture album in the bookstore, which cost a total of a yuan and b points (b can be a two-digit number, here the "corners" are replaced with "fen"). He immediately went home to get money to buy. In his haste, he withdrew b yuan and a cent. After arriving at the bookstore, Xiao Wang discovered the mistake, and the money he took could buy three books and two picture albums. If the price of each book is 3.50 yuan, then what is the price of each album.
小王在书店看上了一本书和一本画册，共需a元b分(b可以是二位数，这里把"角"都换成了"分")．他立即回家取钱去买．由于匆忙，他取了b元a分钱．到书店后小王发现了错误，取去的钱可以买三本书和两本画册．如果书每本售价3.50元，那么，画册每本的售价是多少．
