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

### Instruction:
A country used to have a tax rate of 20%.  They raised it to 30%.  In that same time frame, John went from making 1,000,000 a year to 1,500,000 a year.  How much more does he pay in taxes now compared to then?

### Response:
 ในอัตราภาษี 20% เขาจะต้องจ่าย .2*1000000 = 200000
ตอนนี้เขาจ่าย 1500000*30% = <<1500000*30*.01=450000>>450000
ดังนั้นเขาจ่ายเพิ่มเติม 450000-200000 = $<<450000-200000=250000>>250000
