Answer:
6,400
Step-by-step explanation:
10,000 times 0.045=450 (4.5% of 10,000=450)
450 times 8=3600
10,000-3600=6400
[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &10000\\ r=rate\to 4.5\%\to \frac{4.5}{100}\dotfill &0.045\\ t=\textit{elapsed time}\dotfill &8\\ \end{cases} \\\\\\ A=10000(1-0.045)^8\implies A=10000(0.955)^8\implies A\approx 6918[/tex]
