Write a function for the situation discribed and find the value after 5 yrs. A $12,500 car depreciates 9% each year. Please help

sweet [91]

$\bf \qquad \textit{Amount for Exponential Decay}\\\\
A=P(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &12500\\
r=rate\to 9\%\to \frac{9}{100}\to &0.09\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
A=12500(1-0.09)^t\implies A=12500(0.91)^t
\\\\\\
\textit{after 5 years t = 5}\qquad A=12500(0.91)^5$

and surely you know how much that is.

It cost $20 a day to rent a bike. create an equation using c (cost) and d(days)

BlackZzzverrR [31]

Answer:

$20d = c

Step-by-step explanation:

Since the cost is $20 per day, $20d ($20 for how many days) would be the start of the equation.

C = cost, and $20d will determine the cost, so $20d = c

is your final answer/equation.

Cheers!
