Answer:

x=0.625

Step-by-step explanation:

-(-2x+1)=9-14x

distribute:

2x-1=9-14x

add 1 to both sides

2x = 10-14x

add 14x to both sides

16x=10

divide by 16 to isolate x

x = 0.625

check:

-(-2(0.625)+1) = 9-14(0.625)

0.25 = 0.25

$\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$690.65\\
r=rate\to 7.3\%\to \frac{7.3}{100}\to &0.073\\
t=years\to &\frac{15+31+30+6}{365}
\end{cases}$

the penalty he'll incurred into, since July 6 is after the deadline of April 15, is I = Prt

now "t" is in years, how many days after April 15 to July 6? well, 15 + 31 + 30 +6, to convert to years, divide by 365
