Answer:

$0.7(220-a)=154-0.7a$

Step-by-step explanation:

Given : Expression $0.7(220-a)$

To find : Solve the expression by distributive ?

Solution :

Distributive property is defined as $a(b-c)=ab-ac$

Expression $0.7(220-a)$

Here, a=0.7, b=220 and c=a

Applying distributive property,

$0.7(220-a)=0.7\times 220-0.7\times a$

$0.7(220-a)=154-0.7a$

Therefore, $0.7(220-a)=154-0.7a$

Amanda [17]

So.. in this case, the starting amount is the 500mg sample... and the rate of decay, negative rate, is 1%, and at the time, the elapsed days is 0, to t = 0, P = 400

$\bf \qquad \textit{Amount for Exponential change}\\\\
A=P(1\pm r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{starting amount}\to &500\\
r=rate\to 1\%\to \frac{1}{100}\to &0.01\\
t=\textit{elapsed period}\to &300\\
\end{cases}
\\\\\\
A=500(1-0.01)^{300}$
