Let's analyze the table to determine if there is a proportional relationship between $x$ (number of cans) and $y$ (cost in dollars).

A proportional relationship occurs when the ratio between $y$ and $x$ remains constant. In other words, $\frac{y}{x}$ should be the same for all pairs of values.

Let's calculate the ratio $\frac{y}{x}$ for each pair:

1. For $x = 11$ and $y = 24$, the ratio is $\frac{24}{11} \approx 2.18$.
2. For $x = 36$ and $y = 49$, the ratio is $\frac{49}{36} \approx 1.36$.
3. For $x = 66$ and $y = 79$, the ratio is $\frac{79}{66} \approx 1.20$.
4. For $x = 85$ and $y = 98$, the ratio is $\frac{98}{85} \approx 1.15$.

Since the ratios are not equal, $x$ and $y$ do not have a proportional relationship.

Would you like more details on proportional relationships, or have any questions about this explanation? Here are five related questions for practice:

1. What does a proportional relationship mean in terms of graphing?
2. How would you find the constant of proportionality if a relationship were proportional?
3. Can you calculate the difference in the cost per can as the number of cans increases?
4. What would the equation of a proportional relationship look like?
5. How can you tell if a relationship is linear but not proportional?

Tip: In a proportional relationship, the graph will be a straight line that passes through the origin (0, 0).
