<human>:  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?
<bot>: How much did the third ticket cost? ** The third ticket cost $150/3=$<<150/3=50>>50
How much did the tickets cost? ** So the tickets cost $150*2+$50=$<<150*2+50=350>>350
How much did he pay? ** That means he paid $350/2=$<<350/2=175>>175
How much money did he have left? ** So he had $500 - $175 = $<<500-175=325>>325 left over
