1)

\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+r\right)^{t}
\quad 
\begin{cases}
A=\textit{compounded amount}\\
P=\textit{original amount deposited}\to &\$600\\
r=rate\to 1.6\%\to \frac{1.6}{100}\to &0.016\\
t=years\to &2
\end{cases}
\\\\\\
A=600\left(1+0.016\right)^{2}

3)

\bf V(t)=1350(1.017)^t\implies 
\begin{array}{llllll}
V(t)&=&1350(&1 +& 0.017&)^t\\
A&=&P(&1+&\boxed{r}&)^t
\end{array}

notice the rate "r"... now, is in decimal format, as you saw on 1) is just r/100 so 1.6% was really 1.6/100 or 0.016  anyhow

to get the percentage form, just multiply it by 100

Solve the proportion 35/30 = 28/?<br> A. 48<br> B. 23<br> C. 24<br> D. 46
koban [17]

Answer:

C. 24

Step-by-step explanation:

by algebra:

let "?" be x

35/30 = 28 / x   (multiply both sides by 30)

35 = (28/x) (30)   (multiply both sides by x)

35x = (28)(30)

35x = 840  (divide both sides by 35)

x = 840 / 35

x = 24
