or
represents the change in the goalie's rating points.
Explanation:
It is given that hockey goalie loses
rating points each time his team loses.
If the team loses a game then the change in the goalie's rating points is defined as
![-(13)/(5)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/rp5zgzwxd4flksamy42ip9xyq0ocpeodem.png)
If the team loses 8 games then the change in the goalie's rating points is defined as
![-(13)/(5)* 8](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ig25sb3zl0r71vx53xebz6m0fqid34nicx.png)
![-(104)/(5)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/d2ox2s3xo9ug6konxdej825ontc7600uka.png)
It can be written as
![-20(4)/(5)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/646v3c1o8l2lxuf54q0pbf3oqwmf2paotx.png)
Therefore the number
or
represents the change in the goalie's rating points.
