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

### Instruction:
Van Helsing gets paid by the town to remove all the vampires and werewolves. He gets $5 per vampire and $10 per werewolf. He removes half the vampires and removes 8 werewolves, and earned $105. There were 4 times as many werewolves as vampires. What percentage of the werewolves did he remove?

### Response:
 Acha x iwe idadi ya vampira.
Anapata $80 kutokana na kuwatoa wawindaji kwa sababu 8 x 10 = <<8*10=80>>80
Amejipatia $25 kutokana na kuwatoa vampira kwa sababu 105 - 80 = <<105-80=25>>25
Aliwatoa vampira 5 kutoka mji kwa sababu 25 / 5 = <<25/5=5>>5
Mji ulikuwa na vampira 10 kwa sababu 5 / .5 = 10
Kulikuwa na wawindaji 40 kwa sababu 4 x 10 = <<4*10=40>>40
Uwiano wa wawindaji aliowatoa ni .2 kwa sababu 8 / 40 = <<8/40=.2>>.2
Asilimia ya wawindaji aliowatoa ni 20% kwa sababu 100 x .2 = <<100*.2=20>>20
