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).
-
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.
- From the graph, we can read the following costs per ounce at specific points:
-
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.
- To convert this to cost per ounce, we need to find the cost for some specific ounces:
- Store B's price is given by the equation \(y = 0.13x\).
-
Comparing the Costs:
- Store A: $0.10 per ounce
- Store B: $0.13 per ounce
-
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.
