The question is essentially asking who's equation works better (Part A) and to explain why (Part B). 
Marcella is suggesting the equation 6r + 12 = 683.88 
Julia is suggesting the equation 6(r + 12) = 683.88 

Six people are on the trip.
It is $12 PER person to rent a floatation device. 
The total cost of the trip was $683.88.

Hope I've helped!

Find f(x) if it is known that f(x−6)=12x−72.
zheka24 [161]

Answer:

f(x)=12x

Step-by-step explanation

We know that f(x) is our y-coordinate and x is the x-coordinate

Next we should insert x-6 as x in the equation

This is f(x)=12(x-6)-72

But if you look at this that leads to 12x-72 (ignore y-intercept)

That is our first equation  

This means that if you take out -6 from the x

You will get f(x)=12x

(Also do you go to RSM?)

A cylinder has a volume of 360 in^3. If the height and radius are multiplied by 2.5, what will the resulting volume be?
4vir4ik [10]
\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=2.5r\\
h=2.5h
\end{cases}\implies V=\pi (2.5r)^2(2.5h)
\\\\\\
V=\pi \cdot 2.5^2\cdot  r^2\cdot 2.5h\implies V=(2.5^2\cdot 2.5)\pi r^2 h
\\\\\\
V=15.625\pi r^2h\impliedby \textit{15.625 of the original}
\\\\\\
\textit{if the original was 360}\qquad 15.265\cdot 360
