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

### Instruction:
On a monthly basis, Esperanza pays $600 in rent, 3/5 as much money on food as she pays on rent and her mortgage bill costs three times the amount of money she spends on food. If she saves $2000 and also pays the equivalent of 2/5 of her savings in taxes, calculate her gross monthly salary.

### Response:
 ค่าเช่าของเธอคือ $600/เดือน
ค่าอาหารของเธอคือ $600*3/5 = $360/เดือน
ค่าเงินกู้ของเธอคือ $360*3 = $1080/เดือน
เงินเดือนขั้นต้นของเธอคือ $2000+$1080+$600+$360 = $4340/เดือน
