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

### Instruction:
Tom decides to get a new floor for his room.  It cost $50 to remove the floor.  The new floor costs $1.25 per square foot and Tom's room is 8*7 feet.  How much did it cost to replace the floor?

### Response:
 ห้องมีขนาด 8*7 = <<8*7=56>>56 ตารางฟุต
ดังนั้นพื้นใหม่มีราคา 56*1.25 = $<<56*1.25=70>>70
ดังนั้นค่าใช้จ่ายทั้งหมดคือ 50+70 = $<<50+70=120>>120
