From the graph, we have the costs for Granny Smith apples:
- At 2 pounds: $3.50

- For 3 pounds: $5.25 / 3 = $1.75 per pound
- For 4 pounds: $7.00 / 4 = $1.75 per pound
McIntosh Apples:
- For 2 pounds: $3.70 / 2 = $1.85 per pound
- For 3 pounds: $5.55 / 3 = $1.85 per pound
- For 4 pounds: $7.40 / 4 = $1.85 per pound
Conclusion: Granny Smith apples have a cost of $1.75 per pound, while McIntosh apples have a cost of $1.85 per pound.
