Answer:

Bobby's economic profits for the day is $0.60.

Step-by-step explanation:

Bobby sells 20 glasses of lemonade for $0.20 per cup.

Amount earned = $20\times0.20=4$ dollars

The average total cost is $0.17.

So, difference in selling amount and average = $0.20-0.17=0.03$ dollars

Therefore, Bobby's economic profits for the day is = $20\times0.03=0.60$ dollars

Hence, the answer is $0.60.

Does somebody know the answer? If you can please explain

None of them are correct.
You have to isolate the variable by dividing each side by factors that don't contain the variable.
And when you do so you get a closed point starting at positive 8 and an extending ray to positive infinity and a closed point at -15 with a ray extending to negative infinity on the number line so none of them are correct.

$\bf \qquad \textit{Amount for Exponential Decay}
\\\\
A=P(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &3600\\
r=rate\to 32\%\to \frac{32}{100}\to &0.32\\
t=\textit{elapsed time}\to &5\\
\end{cases}
\\\\\\
A=3600(1-0.32)^5\implies A=3600(0.68)^5\implies A\approx 523.41601$
