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

### Instruction:
 Katika mashindano ya Hisabati, Sammy alipata alama 20, Gab alipata mara mbili ya alama za Sammy, wakati Cher alipata mara mbili ya alama za Gab. Ikiwa wapinzani wao walipata alama 85, wana alama ngapi zaidi kuliko wapinzani wao?


### Response:
 Gab alipata alama 20 x 2 = <<20*2=40>>40.
Cher alipata alama 40 x 2 = <<40*2=80>>80.
Timu yao ilipata alama 20 + 40 + 80 = <<20+40+80=140>>140.
Hivyo, waliipata alama 140 - 85 = 55 zaidi ya wapinzani wao.
