Step 1 :The problem provides us with the function \(P(x)=\frac{100}{1+47 e^{-0.16 x}}\), which represents the percentage of the target audience that buys the game after \(x\) ads are broadcast.
Step 2 :For part a), we need to find \(P(0)\), which represents the percentage of the target audience that buys the game without seeing any ads. Substituting \(x = 0\) into the function, we get \(P(0) = 2.0833333333333335\).
Step 3 :Rounding to the nearest tenth, we get approximately \(2.1\%\). So, the percentage of the target audience that buys the game without seeing any ads is approximately \(\boxed{2.1\%}\).
Step 4 :For part b), we need to find \(P(35)\), which represents the percentage of the target audience that buys the game after seeing 35 ads. Substituting \(x = 35\) into the function, we get \(P(35) = 85.19341841118424\).
Step 5 :Rounding to the nearest tenth, we get approximately \(85.2\%\). So, the percentage of the target audience that buys the game after seeing 35 ads is approximately \(\boxed{85.2\%}\).
