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

### Instruction:
Jeff wanted to rent an apartment to live in for the next 5 years until he finishes his studies. He found a nice apartment next to his school, the owner asks Jeff to pay $300 each month, Jeff agreed, and for the first 3 years everything went fine, but then the owner wanted to raise the price for each month to $350. Jeff agreed again and continued paying until he graduated. How much did Jeff end up paying for the apartment throughout the 5 years?

### Response:
 เจฟจ่าย $300 x 12 เดือน = $<<300*12=3600>>3,600 ต่อปี
เจฟจ่าย $3,600 x 3 = $<<3600*3=10800>>10,800 ในช่วง 3 ปีแรก
ใน 2 ปีสุดท้ายเจฟจ่าย $350 x 12 เดือน = $<<350*12=4200>>4,200 ต่อปี
เจฟจ่าย $4,200 x 2 = $<<4200*2=8400>>8,400 ใน 2 ปีสุดท้าย
เจฟจ่ายเจ้าของทั้งหมด $8,400 + $10,800 = $<<8400+10800=19200>>19,200
