I'm pretty sure it would be d. you have to add the xs and ys and divide each by 2.
Answer:
Constant of proportionality: ![k=3](https://tex.z-dn.net/?f=k%3D3)
Equation: ![c=3d](https://tex.z-dn.net/?f=c%3D3d)
Step-by-step explanation:
By definition, Direct proportion equations have the following form:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
Where "k" is the Constant of proportionality.
In this case, let be "c" the the amount of caffeine consumed (in mg) from a glass of Diet Pepsi and "d" the number of ounces that was drank.
So, the equation that represents this relationship will have this form:
![c=kd](https://tex.z-dn.net/?f=c%3Dkd)
Then, the first step is to find the Constant of proportionality "k".
Knowing that:
![c=24;d=8](https://tex.z-dn.net/?f=c%3D24%3Bd%3D8)
We can substitute values into the equation:
![24=k(8)](https://tex.z-dn.net/?f=24%3Dk%288%29)
Now, solving for "k", we get:
![\frac{24}{8}=k\\\\k=3](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B8%7D%3Dk%5C%5C%5C%5Ck%3D3)
Therefore, we can write the following equation that represents that proportional relationship:
![c=3d](https://tex.z-dn.net/?f=c%3D3d)
