How much did James get a discount on each CD? ** He got a 15*.4=$<<15*.4=6>>6 discount on each CD
How much did each CD cost? ** That means each CD cost 15-6=$<<15-6=9>>9
How much did James pay? ** So he paid 10*9=$<<10*9=90>>90
How much money was he out? ** That means he was out 90-40=$<<90-40=50>>50
