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

### Instruction:
A performing magician has a disappearing act where he makes a random member of his audience disappear and reappear. Unfortunately, one-tenth of the time, the audience member never reappears. However, one-fifth of the time, two people reappear instead of only one. If the magician has put on 100 performances of the act this year, how many people have reappeared?

### Response:
 Mchawi amefanya vitendo 100 / 10 = <<100/10=10>>10 ambapo hakuna mtu ameonekana tena.
Mchawi amefanya vitendo 100 / 5 = <<100/5=20>>20 ambapo watu wawili wametokea.
Mchawi amefanya vitendo 100 - 20 - 10 = <<100-20-10=70>>70 ambapo mtu mmoja ameonekana tena.
Kwa hivyo, kumekuwa na jumla ya 1 * 70 + 2 * 20 = 70 + 40 = <<70+40=110>>110 watu ambao wametokea tena.
