<human>:  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?
<bot>: How many points did Gab score? ** Gab scored 20 x 2 = <<20*2=40>>40 points.
How many points did Cher score? ** Cher scored 40 x 2 = <<40*2=80>>80 points.
How many points did their team score? ** Their team scored 20 + 40 + 80 = <<20+40+80=140>>140 points.
How many more points do they have than their opponent? ** Therefore, they scored 140 - 85 = <<140-85=55>>55 more points than their opponent.
