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

### Instruction:
In a Math competition, Sammy scored 20 points, Gab scored twice as many as Sammy's score, while Cher scored twice as many as Gab's score. If their opponent scored 85 points, how many more points do they have than their opponent?

### Response:
 แก็บได้คะแนน 20 x 2 = <<20*2=40>>40 คะแนน
เชอร์ได้คะแนน 40 x 2 = <<40*2=80>>80 คะแนน
ทีมของพวกเขาได้คะแนนรวมกันเป็น 20 + 40 + 80 = <<20+40+80=140>>140 คะแนน
ดังนั้นพวกเขาได้คะแนนมากกว่าคู่แข่งอีก 140 - 85 = <<140-85=55>>55 คะแนน
