### Instruction:
In a studio audience of 100 people, 40% of these people have an envelope taped underneath their chairs.  20% of these people will have "You Won" in their envelope, the rest will have empty envelopes.  How many people will win a prize?

### Response:
 40% ya kikundi cha watu 100 katika studio watakuwa na bahasha chini ya viti vyao, hivyo .40*100 = <<.40*100=40>>40 watu watapata bahasha.
20% ya watu hawa 40 watapata "Umeshinda" katika bahasha zao, hivyo ni .20*40 = <<.20*40=8>>8 watu watajishindia zawadi.
