Question

An illustration shows Quadrant 1 of a coordinate plane. The x-axis is labeled Ounces and ranges from 0 to 40 in 5 unit increments. The y-axis is labeled Cost in dollars and ranges from from 0.00 to 4.00 in increments of 0.50. The graph is titled Cost per Ounce. A line connects four points plotted on the graph. The coordinates of the plotted points are left parenthesis 0 comma 0 right parenthesis, left parenthesis 8 comma 0.80 right parenthesis, left parenthesis 15 comma 1.50 right parenthesis, and left parenthesis 30 comma 3.00 right parenthesis.

The graph displays the cost per ounce of canned peas. Use the graph to determine the unit rate of the proportional relationship.

Answer 1

To determine the unit rate of the proportional relationship shown in the graph, you need to analyze the coordinates, particularly focusing on the cost per ounce.

From the plotted points:

1. At (0, 0) – 0 ounces cost $0.00
2. At (8, 0.80) – 8 ounces cost $0.80
3. At (15, 1.50) – 15 ounces cost $1.50
4. At (30, 3.00) – 30 ounces cost $3.00

To find the cost per ounce, take the total cost and divide it by the number of ounces:

• For 8 ounces: \[ \text{Cost per ounce} = \frac{0.80}{8} = 0.10 \text{ dollars per ounce} \]

This calculation confirms that the unit rate, or cost per ounce, is $0.10.

Therefore, the correct response is: Canned peas cost $0.10 per ounce.
