The ratio of the price of a bag to the price of a book was 9: 4. During a sale, the prices of the bag and the book were reduced by $7 and $2 respectively. The ratio of the price of the bag to the price of the book became 2: 1. How much was the price of the bag at first?

Bag ==B,    Book==K

 

B / K ==9 / 4

[B - 7] / [K - 2] ==2/1, solve for B, K

 

B==$27 - original price of the bag

K ==$12 - original price of the book
