### Instruction:
 Bobby alifanya supu kubwa yenye uzito wa kilogramu 80. Kila siku, supu hiyo inapungua kwa nusu. Itafikia uzito gani siku ya nne baada ya kuitengeneza?


### Response:
 Siku ya kwanza, supu inapungua hadi 80 * 0.5 = <<80*0.5=40>>40 kg.
Siku ya pili, inapungua hadi 40 * 0.5 = <<40*0.5=20>>20 kg.
Siku ya tatu, inapungua hadi 20 * 0.5 = <<20*0.5=10>>10 kg.
Na siku ya nne, inapungua hadi 10 * 0.5 = <<10*0.5=5>>5 kg.
