<h3>
The missing table is attached.</h3>
Let be "x" the numbers of stars Roberto collects and "y" his total points.
The proportional relationship has this form:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
Where "k" is the constant of proportionality.
We can choose the point
) from the table, where:
![x=8\\y=12](https://tex.z-dn.net/?f=x%3D8%5C%5Cy%3D12)
Substituting these values into
and solving for "k", we get:
Knowing the value of "k", we determine that the following Numbers of stars and the Total points could be used as the missing values in the table:
1) For
:
![y=(1.5)(20)=30](https://tex.z-dn.net/?f=y%3D%281.5%29%2820%29%3D30)
2) For
:
![y=(1.5)(28)=42](https://tex.z-dn.net/?f=y%3D%281.5%29%2828%29%3D42)
3) For
:
![y=(1.5)(38)=57](https://tex.z-dn.net/?f=y%3D%281.5%29%2838%29%3D57)
