The third ticket cost $150/3=$<<150/3=50>>50

So the tickets cost $150*2+$50=$<<150*2+50=350>>350

That means he paid $350/2=$<<350/2=175>>175

So he had $500 - $175 = $<<500-175=325>>325 left over

James gets 3 parking tickets.  The first 2 cost $150 each and the third cost 1/3 as much as one of these.  His roommate agrees to pay half the cost.  How much money does he have left if he had $500 in the bank?
