To determine the unit rate of the proportional relationship from the graph titled "Cost per Ounce," we need to find the cost per ounce by calculating the slope of the line connecting the points.
From the graph, we can see that:
- At 0 ounces, the cost is $0.00.
- At 8 ounces, the cost is $0.80.
- At 15 ounces, the cost is $1.50.
- At 30 ounces, the cost is $3.00.
To find the unit rate (cost per ounce), we can look at one of the points where we know both ounces and cost. For example, we can take the point (8, 0.80):
\[ \text{Unit Rate} = \frac{\text{Cost}}{\text{Ounces}} = \frac{0.80}{8} = 0.10 \text{ dollars per ounce} \]
Thus, the unit rate of the cost per ounce of canned peas is:
Canned peas cost $0.10 per ounce.
