According to the problem, the graph is modeled by the relation
![y=(x)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/t1mcyjwtcee83hu1m5y3laezhzc5be7n1h.png)
So, we can observe that x-values refer to cups of hot chocolate, and y-values refer to price in dollars.
If we need to find the proce for 6 cups of hot chocolate, we just need to replace
into the given relation, as follows
![y=(6)/(4)\\y=1.5](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qi110000iqo04sq6ycfssks0z653r2a8zx.png)
Therefore, 6 cups of hot chocolate cost $1.50.
