To determine the unit rate of the proportional relationship from the graph, we need to look at the cost per ounce.
From the points plotted:
-
At \( (8, 0.80) \): Cost = $0.80 for 8 ounces. To find the cost per ounce, divide \( 0.80 \) by \( 8 \): \[\frac{0.80}{8} = 0.10\]
-
At \( (15, 1.50) \): Cost = $1.50 for 15 ounces. To find the cost per ounce, divide \( 1.50 \) by \( 15 \): \[\frac{1.50}{15} = 0.10\]
-
At \( (30, 3.00) \): Cost = $3.00 for 30 ounces. To find the cost per ounce, divide \( 3.00 \) by \( 30 \): \[\frac{3.00}{30} = 0.10\]
In each case, the unit rate (cost per ounce) is consistently \( 0.10 \).
Therefore, the correct response is:
Canned peas cost $0.10 per ounce.
