I need help can someone please teach me thee ways of math :/​

Answer 1

the bus value is depreciating, thus is Decay

`\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &250000\\ r=rate\to 20\%\to (20)/(100)\dotfill &0.2\\ t=years \end{cases} \\\\\\ A = 250000(1 - 0.2)^(t) \implies \boxed{A = 250000(0.8)^t} \\\\\\ \stackrel{\textit{after 6 years, t=6}}{A=250000(0.8)^6}\implies \boxed{65536}`
