To determine which store offers the better buy for canned corn, we need to evaluate the cost per ounce for both Store A (based on the graph) and Store B (based on the equation).
1. **Store A's Costs**:
- From the graph, we can read the following costs per ounce at specific points:
- At 0 ounces: $0.00
- At 8 ounces: $0.80 (which is $0.10 per ounce)
- At 15 ounces: $1.50 (which is $0.10 per ounce)
- At 30 ounces: $3.00 (which is $0.10 per ounce)
- Analyzing the values, the cost per ounce for Store A appears to be $0.10.
2. **Store B's Costs**:
- Store B's price is given by the equation \(y = 0.13x\).
- To convert this to cost per ounce, we need to find the cost for some specific ounces:
- For example, for 1 ounce:
\[
y = 0.13 \times 1 = 0.13
\]
This means Store B costs $0.13 per ounce.
- This calculation holds for any given quantity of ounces.
3. **Comparing the Costs**:
- Store A: $0.10 per ounce
- Store B: $0.13 per ounce
4. **Conclusion**:
- Store A is cheaper than Store B by:
\[
0.13 - 0.10 = 0.03
\]
Therefore, the response is:
**Store A has the better buy by $0.03 per ounce.**
1. **Store A's Costs**:

- At 30 ounces: $3.00 (which is $0.10 per ounce)
- Analyzing the values, the cost per ounce for Store A appears to be $0.10.
2. **Store B's Costs**:
- Store B's price is given by the equation \(y = 0.13x\).
- To convert this to cost per ounce, we need to find the cost for some specific ounces:
- For example, for 1 ounce:
\[
y = 0.13 \times 1 = 0.13
\]
This means Store B costs $0.13 per ounce.
- This calculation holds for any given quantity of ounces.
3. **Comparing the Costs**:
- Store A: $0.10 per ounce
- Store B: $0.13 per ounce
4. **Conclusion**:
- Store A is cheaper than Store B by:
\[
0.13 - 0.10 = 0.03
\]
Therefore, the response is:
**Store A has the better buy by $0.03 per ounce.**
