Answer:

The answer to your question is: letter B

Step-by-step explanation:

Data

°C °F

0 32

35 95

Process

Find slope m = (95 - 32) / ( 35 - 0)

m = 63 / 35

m = 9/5

Line equation

( y - y1) = m(x - x1)

y = °C x = °F

°C - 0 = 9/5 ( °F - 32)

°C = 9/5( °F - 32)

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

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
