SOLUTION

We want to find the unit rate for number of cookies per dollar. This can be done using the diagram below

So the unit rate is calculated thus

$\begin{gathered} \text{Unit rate = }\frac{rise\text{ }}{\text{run}} \\ =\frac{14\text{ cookies }}{7\text{ dollars }} \\ =\frac{14}{7} \\ 2\text{ cookies per dollar} \end{gathered}$
