Given: The number of people said football is their favorite sport=210
The percent of people represent football = 42%=0.42
Let x be the total number of people surveyed .
Then according to the question,
[tex]42\%\ of\ x=210\\\Rightarrow\ 0.42x=210\\\Rightarrow\ x=\frac{210}{0.42}\\\Rightarrow\ x=500[/tex]
hence, the total number of people survey is 500.
