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

### Instruction:
Marcus wants to buy a new pair of shoes. He decided to pay not more than $130 for them. He found a pair for $120, on which he got a discount of 30%. How much money will he manage to save by buying these shoes and not spending the assumed maximum amount?

### Response:
 ส่วนลดสำหรับรองเท้าที่มาร์คัสพบคือ 120 * 0.3 = $<<120*0.3=36>>36
ดังนั้นเขาต้องจ่ายเพียง 120 - 36 = $<<120-36=84>>84
นั่นหมายความว่าเขาสามารถประหยัดได้ 130 - 84 = $<<130-84=46>>46
