John had a sum of money. He spent $132 on a computer software and 3/4 of his

remaining money on 5 indentical books. The amount he had left wa equal to 1/6 of his

money. How much did each book cost?

x - [132 + 3/4(x - 132)] = x/6

 

x = 396

 

The cost of all 5 books =>      3/4(396 - 132) = 198
