Hey there! :)

Answer:

2nd choice.

Step-by-step explanation:

Given:

630 = 42f.

Divide both sides by 42 to solve for f:

630/42 = 42f/42

f = $15.

This equation is not an inequality, so a line would not be graphed on the number-line. The proper way to show a single solution would be with a point. Therefore:

The second choice is correct. The number line has a single point at f = 15.

Deep's property tax is $690.65 and is due April 15. He does not pay until July 6. The county adds a penalty of 7.3% simple int

bazaltina [42]

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

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
