$\bf \textit{Periodic Exponential Decay}\\\\
A=I(1 - r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\\
p=period
\end{cases}$

we know, the first year she sold 400 units, thus year 0, 400 units, t = 0, A = 400.

$\bf \textit{Periodic Exponential Decay}\\\\
A=I(1 - r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &400\\
I=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\to &0\\
p=period
\end{cases}
\\\\\\
400=I(1-r)^{\frac{0}{p}}\implies 400=I\cdot 1\implies 400=I$

therefore then

$\bf \textit{Periodic Exponential Decay}\\\\
A=I(1 - r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &400\\
r=rate\to 20\%\to \frac{20}{100}\to &0.20\\
t=\textit{elapsed time}\\
p=period\to &2
\end{cases}
\\\\\\
A=400(1-0.2)^{\frac{t}{2}}$

now, how many units will it had decreased by the 9th year? t = 9

$\bf A=400(1-0.2)^{\frac{9}{2}}$

They obviously didn't get the family membership pass.
Let c be the number of children, a be the number of adults
5c+30a=185
c+a=12 =>c=12-a
5(12-a)+30a=185
60-5a+30a=185
25a=125
a=5
c=12-5=7
there are 7 children and 5 adults.
