$~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill & \$100000\\ P=\textit{original amount deposited}\\ r=rate\to 6.6\%\to \frac{6.6}{100}\dotfill &0.066\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{semiannually, thus two} \end{array}\dotfill &2\\ t=years\dotfill &20 \end{cases}$

$100000=P\left(1+\frac{0.066}{2}\right)^{2\cdot 20}\implies 100000=P(1.033)^{40} \\\\\\ \cfrac{100000}{1.033^{40}}=P\implies 27288.97\approx P$

Please help me. I have an idea of what the answer might be but I’m not sure so I need you to help me clarify if I was correct so

Hello!

<em>According to the diagram, your answer is</em> <em>D.) Some Elephants have tusks</em>

If the entire circle labeled "Elephants" was inside the circle labeled "Animals With Tusks," it would be A, but that is not the case. only part of it is inside. so D is the correct answer.

I hope this helps, and have a nice day!
