Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
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?

### Response:
 ตั๋วที่สามมีราคา $150*1/3=$<<150*1/3=50>>50
ดังนั้นรวมกันตั๋วทั้งหมดมีราคา $150*2+$50=$<<150*2+50=350>>350
นั่นหมายความว่าเขาจ่าย $350/2=$<<350/2=175>>175
ดังนั้นเขาจะเหลือ $500-$175=$<<500-175=325>>325
