8. Suppose the atmospheric air pressure at sea level is about 105 kilopascals. For every, 1000-m increase in altitude, the pressure decreases about 11.5%. What's the approximate pressure at an altitude of 3000 m?

Answer 1

hmmm anyhow, montly, means, 12 times in a year, thus, the cycle is 12 = n
thus \(\qquad \textit{Compound Interest Earned Amount}\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\qquad
\begin{cases}
A=\textit{current amount}\\
P=\textit{original amount deposited}\to &\$3,700\\
r=rate\to 3.3\%\to \frac{3.3}{100}\to &0.033\\
n=\textit{times it compounds per year}\to &12\\
t=years\to &5
\end{cases}\)
